Homework Statement A screenshot of the problem: imgur link: https://i.imgur.com/ljtoclm.png Homework EquationsThe Attempt at a Solution My first attempt at the solution was this: imgur link: https://i.imgur.com/TJcvOzy.jpg However, I have access to the worked solution, and it is...

Homework Statement Control systems subject. Have a DC motor setup on a difference op-amp, then with gain, and the axel moves a wiper on a pot used for feedback. I understand the concepts reasonably well enough to complete the assignment. I'm using MATLAB scripts to approximate parameters...

Homework Statement https://i.imgur.com/WPAKuf4.png seeking G(s) = \frac{\theta_2(s)}{\tau(s)} Homework EquationsThe Attempt at a Solution What does it mean when the viscous drag is parallel to the axis of rotation?[/B] It also turns out that this system needs two equations. I can sort...

In an assignment I have, we are told to implement a Frequency Modulating function without using any of MATLAB's in-built functions, and not to use it's integration function either (use cumsum instead). I've been getting a lot of problems trying to solve these assignment problems without telling...

No. The entire point of the project is to get experience with FPGAs and VHDL and Vivado.

It's a student project for vacation research, under-grad, not sure how many of us, there'll probably be 4-6, we're motivated. My original proposal was to get an FPGA (on an Artix-7 or Z-board) to run a CID camera sensor as a dumb peripheral, do some basic image processing stuff on it (perhaps...

ie: http://m.eet.com/media/1072296/RFFig84.jpg I am 99% sure the answer is: no, it can't. I've read that DSB-SC demodulation requires the carrier frequency to be put back into the signal at the receiving end prior to demodulation (or as part of the demod process), and that if its too out of...

Reduced Instruction Set vs Complex Instruction Sets for the CPU control logic. In the first half of the nand2tetris course a series of projects lead me through describing a very basic CPU from the nand gates up in a basic custom HDL. The CPU I eventually described was actually a Harvard...

I know very basically what pipe-lining is. My understanding is that the output from one "computing element" (usually a small set of instructions solving a simple task, such as say, finding a geometric mean) should flow immediately into the input of the following "computing element" where it is...

The x[n] is there as an impulse at time 0 and 1, at t = 0 the impulse is 1 and t = 1 the impulse is 7. if n <= 0: return 1.0 if n == 1: return 7.0

Homework Statement Find the closed form of the impulse response of the system y[n] = 7y[n-1]-12y[n-2]+x[n] using the peel away and guess method. Ie, by using Python code to find the geometric ratios and amplitudes of the outputs as n grows large, then calculate residuals, and find the...

Homework Statement I have a question related to taking the logs of transfer functions, getting the individual Bode plots of each subsequent factor, and adding those plots graphically. I'm working from Fundamentals of Electric Circuits, 5th edt. Let me start with the following screen capture...

Homework Statement Hello, I am currently doing some holiday pre-study for signals analysis coming up next semester. I'm mainly using MIT OCW 6.003 from 2011 with some other web resources (youtube, etc). The initial stuff is heavy on the old infinite series stuff, that seems often skimmed...

Homework Statement imgur link: https://i.imgur.com/9jozS67.png Homework Equations The Attempt at a Solution [/B] Shouldn't I use V_{rms} = \sqrt{\frac{1}{T}\int_T v^2 dt}? Which would be \sqrt{\frac{100}{2\pi}\int_0^{2\pi/100}(20+60cos(100t))^2dt} This equals \approx 79.88 V The...

Homework Statement I am given this beam: imgur link: http://i.imgur.com/tw6EEJz.jpg and asked to express the slope at A and the max deflection in terms of a, E, I, and Mo. I am being told that my answer has the wrong multiplier...so I assume that my overall approach is ok (??) but I've...
