Homework 30 ECE201: Linear Circuit Analysis Due in class: Friday, November 11, 2011 Question 1 Add the complex numbers j /4 1 z 10e   and j5 /8 2 z 5e   . Express your answer (a) in real and imaginary parts, and (b) as a magnitude and phase. Draw z 1 , z 2 and z 1 + z 2 on the complex plane. Label the real part, the imaginary part, and magnitude and the phase of z 1 + z 2 . Hints (you should be able to solve the previous problem without the hints. Please refrain from reading the hints unless you have invested significant effort). You are not required to write up answers for the questions in this hint. 1. The basic formula for complex number representation for real values is the Euler’s formula: cos sin j e j . This formula allows you to transfer a complex number in polar form into or real and imaginary parts. You need to memorize it for the duration of ECE 201. 2.
