**Assignment 1:**

__Problem 5(d):__ Any hints for this question?  I know we can use Euler's formula to express sin(x)as [e^(jx) - e^(-jx)] / 2.  
Is this what you're looking for?

Answer: This is one way of solving the summation. You can follow this approach.

__Problem 7:__ What do you mean by "analytically"?  Does this mean, using the DTFT tables?

Answer: Analytically implies using the definition of the DTFT and solving the summation.

__Problem 8:__ You want us to take the DTFT of both x[k] and h[k] to obtain X(e^jw) and H(e^jw), multiply them together, then take the inverse DTFT?

Answer: Absolutely.

__Problem 10:__ You want us to take the z-transform of both x[k] and h[k] to obtain X(z) and H(z), multiply them together, then take the inverse z-transform?

Answer: Absolutely.
