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.

Objective: Persuade readers that they should fear a threat of your choosing, real or fabricated. Due Date: Wednesday, November 18th Length: 4-5 pages Format: typed, double-spaced, standard font and margins For this essay, you will be putting together all the aspects of argument that we have been learning about over the last few weeks. You will be using those elements to convince your readers that some issue of your choosing is a threat to them. This issue can be a real threat that you believe people should actually be aware of, or it can be a threat that is not real but that you treat as real (whether it be a fictional/legendary threat or something that is perhaps a small threat but that you present as a big one). Your job is to convince your audience to take this threat seriously, and to do that, you will need to make use of emotional appeal (especially to fear—think back to essays one and two), logical appeal (partly use of details/facts/ evidence we discussed in essay four, but also through definition such as we worked on in essay three), and ethical appeal (your own credibility—think back to issues besides logic and evidence covered in essay four). You may choose to include outside sources if you wish, but you must cite them if you use them and indicate when you are using the words of the original source. We will discuss how to find and to cite them to prepare you to use them correctly. If writing about a fictional threat, you may wish to make up sources. If you do so, I leave it up to you whether you formally cite them (though you must do this if you are using real sources) or informally refer to them in a manner similar to what we saw in the articles we read for essay four. Turning in an essay in which significant portions are not written by you and/or without outside sources cited will result in an essay grade of zero (and not revisable for a higher grade). If you are unsure what to cite, let me know. For ideas, you may want to browse the website snopes.com. This site contains lists and research about many feasible topics for this essay. Try not to use Snopes itself as a source—most entries there contain a list of sources that would be more appropriate for you to utilize and credit in your research. You may also choose to write about a topic covered by one of the essay four articles—if you liked an issue but felt that the warning about it was not very credible, you can use this paper as an opportunity to write about that topic but in a believable, convincing way. Whatever you choose as your topic, by the end of it, you want your reader to believe that what you discuss is a real threat to them.

1 Mixed Session: Basic System Modeling ENGG300 – Engineering Project Practice Abstract— In this mixed session, you will develop some models for items which, perhaps, you are quite familiar with using both theory and experience. A later mixed session in this unit will refine some of these models. I. INTRODUCTION When confronted with a requirements document or a problem in general, the engineer must develop a solution which is rooted in both theory and practice. In applying any theoretical principles, there is often times underlying mathematics which represents that theory, such as Ohm’s law relating voltage and current or even a simple calculation of adding up the size of all sub-components to figure out the volume of the overall system. Where practice, or experience, is applied (using figures of merit or rules-of-thumb), there is often a simple calculation that can be done. A good example of this is Moore’s Law if you need to predict computing power into the future. Either way, we refer to this as system(s) modeling or simply modeling. At this level of detail, it is sometimes referred to as ”back of the envelope”. In this mixed session, you will develop some models for items which, perhaps, you are quite familiar with. Despite its reputation as a ”business” tool, you will use a spreadsheet program. A later mixed session in this unit will refine some of these models. II. TELECOMMUNICATIONS INFRASTRUCTURE PLANNING The venerable ”utility pole” has been a staple of the telecommunications industry dating back to the days of the telegraph. Proper planning of installing and maintaining this vital piece of infrastructure continues to this day. 1. What is your pre-work value for the distance between utility poles? 2. How many utility poles would be needed to span 1 km? 3. Plot the number of poles needed to span 1 km on a single graph for this and at least 2 other ”reasonable” spacings (i.e. 20% variation). 4. Comment on the nature of this model (i.e. what is the relationship of output to input). III. COMPOUND INTEREST Fixed income investment vehicles, like a savings account at a bank, pay a percentage of the investment back into the account each payment period as ”interest.” 1. For an initial investment of $1000 and interest paid annually in the amount of 5%, create a model in excel of 4 yearly payments. 2. Modify your model so that the 5% is annual, but paid in 4 quarterly payments. Discuss the difference in your results. 3. Develop a more compact mathematical model from your findings. 4. Plot the value of your investment as a function of the time on a single graph for this and at least 2 other interest rates. 5. Comment on the nature of this model (i.e. what is the relationship of output to input). IV. DRAM AREA PLANNING The Dynamic Random Access Memory (DRAM) Integrated Circuit (IC) has been the focus of an amazing feet of engineering for over 4 decades. Driven by and as a result of Moore’s Law, the DRAM has been at the forefront of every new generation of IC technology dating back to the early days of the personal computer. Each new generation of manufacturing technology, or ”node” is defined by a ”critical dimension”, or CD, which is the smallest feature that can be manufactured in that process. For example, the 3 μm node has a CD and minimum feature size of 3 μm. A DRAM ”cell” is essentially a capacitor defined by the CD. To address the DRAM cells arranged as a matrix or array on the IC, a rowcolumn addressing scheme can be used to uniquely define a single cell, or bit, that is being addressed. DRAM ICs normally come in densities (i.e. number of cells) that are powers of 2, and corresponding to the number of bits in the address. 1. Assuming that the addressing logic scales proportionally with the CD and as a proportional sum of the number of cells in a row and the number of columns, discuss the optimal arrangement of the cells in terms of number of rows and number of columns. 2. For the 1 μm node, calculate the chip size as a function of density (in powers of 2) if the constants of proportionality for the row and column addressing logic are both 20. Plot from 28 to 224. 3. Repeat on the same graph for the .1 μm node and the .01 μm node. 4. Discuss any interesting features of the model as a function of density and as a function of node. Does considering density as an integer versus a power of 2 make a difference in your model and why? 5. Comment on the nature of this model (i.e. what is the relationship of output to input).
