Discussion related to HW1 (ECE438BoutinFall09)

I think the ROC for question 7a is incorrect. Should be |z| < 1/2.

  • Nope, ROC is correct. Look at the second example I did on Friday and use the same trick. --Mboutin 18:12, 7 September 2009 (UTC)

For problem 7d, the differentiation property might help. However, the ROC defined in the problem seems wierd. Negative magnitude? :(

  • Oops! Yeah the ROC was supposed to be $ |Z|<1 $. But, technically, the statement is correct, just a bit weird. --Mboutin 18:12, 7 September 2009 (UTC)
