• You might want to review the following pages before doing the homework. Do you see any mistake/misleading statements in them? --Mboutin 09:24, 11 September 2009 (UTC)
  • Animated aliasing example
  • page on sampling theorem
  • another page on sampling theorem
  • another page on sampling theorem
  • page on sampling
  • page on impulse-train sampling
  • page on sampling with zero-order hold
  • another page on zero-order hold sampling
  • please list other relevant pages.

• Hi,can we use MATLAB for the homework?

For example, for Question 1, I obtained the Fourier transform in terms of the general zeros and poles, and then replaced, say z1 by r1.exp(jw1), where r1 and w1 are constants.

Now, for an approximate plot, do I fix r1 and w1, as the values that correspond to the approximate location of the zero/pole, or do I let them remain general.

Basically, it's a mean looking function, and for an approximate plot, I was tempted to use MATLAB to plot it. Can I do that? --Dlamba
