Biomedical Signal and Image Processing (4800_420_001) Assigned on September 12th, 2017 Assignment 4 – Noise and Correlation 1. If a signal is measured as 2.5 V and the noise is 28 mV (28 × 10−3 V), what is the SNR in dB? 2. A single sinusoidal signal is found with some noise. If the RMS value of the noise is 0.5 V and the SNR is 10 dB, what is the RMS amplitude of the sinusoid? 3. The file signal_noise.mat contains a variable x that consists of a 1.0-V peak sinusoidal signal buried in noise. What is the SNR for this signal and noise? Assume that the noise RMS is much greater than the signal RMS. Note: “signal_noise.mat” and other files used in these assignments can be downloaded from the content area of Brightspace, within the “Data Files for Exercises” folder. These files can be opened in Matlab by copying into the active folder and double-clicking on the file or using the Matlab load command using the format: load(‘signal_noise.mat’). To discover the variables within the files use the Matlab who command. 4. An 8-bit ADC converter that has an input range of ±5 V is used to convert a signal that ranges between ±2 V. What is the SNR of the input if the input noise equals the quantization noise of the converter? Hint: Refer to Equation below to find the quantization noise: 5. The file filter1.mat contains the spectrum of a fourth-order lowpass filter as variable x in dB. The file also contains the corresponding frequencies of x in variable freq. Plot the spectrum of this filter both as dB versus log frequency and as linear amplitude versus linear frequency. The frequency axis should range between 10 and 400 Hz in both plots. Hint: Use Equation below to convert: Biomedical Signal and Image Processing (4800_420_001) Assigned on September 12th, 2017 6. Generate one cycle of the square wave similar to the one shown below in a 500-point MATLAB array. Determine the RMS value of this waveform. [Hint: When you take the square of the data array, be sure to use a period before the up arrow so that MATLAB does the squaring point-by-point (i.e., x.^2).]. 7. A resistor produces 10 μV noise (i.e., 10 × 10−6 V noise) when the room temperature is 310 K and the bandwidth is 1 kHz (i.e., 1000 Hz). What current noise would be produced by this resistor? 8. A 3-ma current flows through both a diode (i.e., a semiconductor) and a 20,000-Ω (i.e., 20-kΩ) resistor. What is the net current noise, in? Assume a bandwidth of 1 kHz (i.e., 1 × 103 Hz). Which of the two components is responsible for producing the most noise? 9. Determine if the two signals, x and y, in file correl1.mat are correlated by checking the angle between them. 10. Modify the approach used in Practice Problem 3 to find the angle between short signals: Do not attempt to plot these vectors as it would require a 6-dimensional plot!

Project Four: Revisiting English 1010 (Literacy, Language, and Culture: An Exploration of the African American Experience) The MultiMedia Reflective Portfolio Project Overview This project will provide us with the opportunity to use a combination of textual, digital, and oral tools to: 1) reflect on and display what we have learned about African American literacy, language, and culture; and 2) reflect on and display what we have learned about the process of composing a literacy narrative, informative summary, media analysis, and multimedia reflective portfolio project. Ultimately, this project will provide us with the opportunity to use multimedia tools and applications to reflect on and display our experience as knowledge users and knowledge makers in this course (specifically as it relates to the English 1010 Learning Outcomes). ___________________________________________________________________ Introduction/Rationale/Assignment Prompt: This reflective assignment, which is the last major assignment of the semester, consists of two parts: Part One Part One consists of a 2-3 page reflective essay in which you reflect on and display: (1) what you learned about African American literacy, language, and culture; and (2) what you learned about the process of composing a literacy narrative, informative summary, media analysis, and multimedia reflective portfolio project–specifically as the process relates to the Learning Outcomes (Reading, Writing, Reflection, and Technology Use). To do so, you must look back over the work you produced during the semester in order to locate and discuss your learning and accomplishments in these areas. While your discussion of achievements with respect to ENG 1010 Learning Outcomes is perhaps the most important goal in the Reflective Essay, the written expression of these achievements can be strengthened when it is integrated into a broader narrative that describes where you are coming from and who you are as a student. In this narrative, you may discuss, for example, how you learned and used various reading strategies in the course, or you may describe, for example, how your ability to use composition and course management technologies, like Word and Blackboard, increased. You may also address, as appropriate, how your culture, identity, or background shaped your experiences as a student in ENG 1010. You may wish to discuss, for example, some of the following issues. • Transition to college and the larger first-year experience • Negotiation of a new identity as college student (how you adjusted; how you handled it) • Membership in groups historically underrepresented in college • Language diversity • Managing life circumstances to be able to give enough time and energy to academic work In sum, the Reflective Essay should make claims about your learning and accomplishments with respect to the two areas identified above. Essentially, the reflective essay should demonstrate what you have learned and what you can do as a result of your work in ENG 1010. In this way, a successful Reflective Essay will inspire confidence that you are prepared to move forward into your next composition courses, beginning with ENG 1020, and into the larger academic discourse community. Part Two Part Two consists of an electronic multimedia portfolio containing 3-5 selected pieces of the work you produced this semester (essay topic proposals, reading responses, essay outlines, essay first or final drafts, in-class assignments, etc.) that you can use as evidence of your learning and accomplishments and to support the claims you made in your reflective essay. ___________________________________________________________________ English 1010 Learning Outcomes Reading ● Develop reading strategies to explain, paraphrase, and summarize college-level material. ● Analyze college-level material to identify evidence that supports broader claims. Writing ● Plan and compose a well-organized thesis-driven text that engages with college-level material and is supported by relevant and sufficient evidence. ● Develop a flexible revision process that incorporates feedback to rewrite multiple drafts of a text for clarity (e.g. argument, organization, support, and audience awareness). Reflection ● Use reflective writing to evaluate and revise writing processes and drafts ● Use reflective writing to assess and articulate skill development in relation to course learning outcomes. Technology Use ● Navigate institutional web-based interfaces, such as course websites, university email, and Blackboard Learn™, to find, access and submit course material. ● Use computer-based composition technologies, including word processing software (e.g. Microsoft Word, PowerPoint), to compose college-level texts. ● Use computer-based composition technologies to read and annotate course readings and texts authored by students (e.g. peer review). Your Final Draft Should: • meet the requirements as outlined in the “Introduction/Rationale/Assignment Prompt” section above. Points for This Project • First Draft: 20 Points • Final Draft: 130 Points • Oral Presentation: 30 Points Refer to the Course Schedule (Syllabus) for Assignment Due Dates. _______________________________________________________________ Evaluation: You will be evaluated based on content, organization, and mechanics.

Lab on Confidence Intervals The story: Studies have shown that the random variable X, the processing time required to do a multiplication on a new 3-D computer, is normally distributed with mean and standard deviation 2 microseconds. A random sample of 16 observations is to be taken (i.e. 16 random multiplications will be performed and the time that it takes to perform each one of them will be annotated). The sample mean will be calculated. Part 1- The very basics 1. Before we collect the random sample, what can we say about the sampling distribution of ? 2. Before we collect the random sample, what is the probability that the sample mean will have a value that is greater than or equal to , and less than or equal to In other words, what is the probability that the sample mean is within 0.98 microseconds ( ) of the true (unknown) mean time? 3. A random sample was taken (i.e.16 multiplications were done) and the processing times were as follows: 42.65 45.15 39.32 44.44 41.63 41.54 41.59 45.68 46.50 41.35 44.37 40.27 43.87 43.79 43.28 40.70 Round the times to the nearest tenth (e.g. 42.65 ~ 42.6) and do the stem-and-leave display Do the stem and leaf display. Calculate the sample mean 39 40 41 42 43 44 45 46 4. Now we will use our knowledge of the value of the sample mean for this particular sample and the relationship between sample means (in general) and population mean (see questions 1 and 2 of this lab) to make an intelligent guess (estimation) of the population mean. Use the formula to calculate a 95 % confidence interval for the population mean (Show your work) ( , ) From the Minitab menu, use STAT>BASIC STATISTIC>ONE SAMPLE Z to check your calculations. Calculate the width of the confidence interval _______________ 5. Interpret the confidence interval you just found: We are 95% confident that the true mean processing time required to do a multiplication on a new 3-D computer lies between __________ and __________ microseconds. (The meaning of this is the following: Think of all the possible samples (all the possible sets of 16 multiplications) that we could have been done with this type of computer; 95% of those samples would have produced confidence intervals that contain the true mean, the other 5% would have been off)
