Unformatted text preview: ECE 2300 CIRCUIT ANALYSIS HOMEWORK #9 1. A complex number with a phase between 90 and 180 (in the 2 nd quadrant) is added to a second complex number with a phase between 90 and 180 (in the 3 rd quadrant). What is the sign of the real part of this sum? 2. A complex number with an arbitrary real part and a positive imaginary part is multiplied by a second complex number that is imaginary, with a negative coefficient for j . What can you say about the product? 3. Solve the following equation for m and n . You should assume that m and n are real numbers. The variable n is an angle, and you should show your units.
