Which data set should I trust more?
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...- kostoglotov

Nyquist and FM and Signal Mixing....
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...- kostoglotov

Holiday project goals for undergrads with an FPGA?
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...- kostoglotov

Can a basic envelope detector demodulate a DSB-SC signal?
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...- kostoglotov

Why is pipelining easier on a RISC vs a CISC?
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...- kostoglotov

Why is pipelining easier on a RISC vs a CISC?
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...- kostoglotov

Finding the closed form of a recursive LTI system
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- kostoglotov

Finding the closed form of a recursive LTI system
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.
