-====== General ======+---- 
 +**Assignment 1:**
  
-===== Do need to register for a CSE Computer Account=====+__Problem 5(d):__ Any hints for this question?  know we can use Euler's formula to express sin(x)as [e^(jx) - e^(-jx)] / 2.   
 +Is this what you're looking for?
  
-Yes.+Answer: This is one way of solving the summation. You can follow this approach.
  
-===== Do I need to attend class=====+__Problem 7:__ What do you mean by "analytically"?  Does this mean, using the DTFT tables?
  
-If you wish to pass.+Answer: Analytically implies using the definition of the DTFT and solving the summation.
  
-====== Tests ======+__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?
  
-===== Do I need to write all tests=====+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. 
 +----
  
  
-... but of course.
