ELE 360 Communication Systems Homework 1. A square wave of 1KHz represents a data stream with “1” and “0”, where “1” is 1V and “0” is -1V. This data stream AM modulates a carrier with a modulation index of 0.8. The carrier amplitude is 4V and its frequency is 1MHz. a. Sketch the wave as a function of time b. What is the average power of the modulated wave?
