1. A sequence of alternating 1s and Os is transmitted as a square wave. What is the fundamental frequency and how many harmonics can be used if the available BW is 100 MHz and a data rate of 56 Mbps is desired? Express the signal as a mathematical function of time (s(1)) and sketch the resulting signal in both the time and frequency domains. Is this a "good enough" representation of the square wave? Why or why not?
