EE 250 Winter 2010 University of Alberta HOMEWORK 4 (due Monday Feb 1st, 2010) Instructor : Karthik Shankar (Make sure your answers show the work in solving the problem. If the final answer is wrong, partial credit will be provided if the work is shown to have made progress towards the solution. Do not expect any credit if the T.A. cannot logically follow what you have put on your submitted homework) 1. Following the example of the DC current source, convert the following time domain forcing functions into generalized phasors and find sin each case. 2. For each amplitude and phase angle in the first column and complex frequency sin the second column, find the corresponding time function. 3. 1
