Computer Engineering is a standard Degree Program in many Canadian Universities. See the below links for some examples. http://www.engineering.uAlberta.ca/ece/ http://www.engineering.uwaterloo.ca/departments.html Also Power Engineering is always in demand in Alberta.

Hey Everyone, I cannot seem to find an way in Matlab to convert a number which has a real and imaginary part in cartesian form into polar form and then express the polar representation on the output. Ex. Convert z=0.1602932442+0.8277219859*j Into 0.8431<79.04 deg (without using...

I remember my prof talking about how if everyone in New York screamed or yelled as loud as they possibly could and you could somehow contain this energy you would barely be able to light up a lightbulb.

I am having a problem with plotting Bode plots in Matlab. We are required to plot a e^(-sT) (simple time shift) as a Bode plot. The "bode" function in Matlab requires either a TF, ZPK, SS, or FRD system as its first input. I cannot seem to find out how to plot the exponential. I can easily plot...

Is it possible to design voltage dividers that do not primarily use resistors. Could you make a <1 voltage gain amplifier? What is usually done in real applications? Thanks

Ya in the frequency domain it becomes autocorrelation. But is that the only way?

I am having a little trouble. I am asked to evaluate the Fourier transform of a periodic train of triangle shaped pulses. Then I have to evaluate the power spectral density. Now it is very easy to find the Fourier transform of one of the triangles, but what do I do when it is periodic? Do I...

This is a quick graphing question. We have to graph Vout/Vin versus the log of frequency. Now the Vout/Vin would have no units but what about the log of frequency? Is it hertz or is it also unitless?

I am also taking a Signals Class right now. When studying for my midterm I stumbled upon this site http://www.jhu.edu/~signals/convolve/ . I found that the actual integral way of convolution is very easy but in some cases such as the convolution of general shapes you have to do it graphically...

Here are two general questions How would you find the period of: sin(2Pi*t)+sin(4Pi*t) or cos(3t)sin(2t) Thanks

well good question. I expanded that equation and then threw it in a k-map. I got the exact expanded equation back. I would say that that equation is the simplest form. Hopefully someone can back me up. my kmap was sum of m(4,8,12,13,14).

Can you prove that 0!=1 or is it just an assumption?
