A sequence of alternating 1s and 0s is transmitted as a square wave. What is the fundamentalfrequency and how many harmonics can be used if the available BW is 100 MHz and a data rate of 56Mbps is desired? Express the signal as a mathematical function of time (s(t)) and sketch the resultingsignal in both the time and frequency domains. Is this a “good enough” representation of the squarewave? Why or why not?
