Consider a QAM communication system that employs raised cosine pulse shapingat the transmitter and a carrier frequency of 2GHz. In this problem you will answer various questionsabout the relationships between symbol rates and bandwidths. Hint: Refer to Lecture 4 slides.1) Suppose that the symbol rate is 1 Megasymbol per second and that the raised cosine pulse shapehas 50 percent excess bandwidth. What is the baseband absolute bandwidth?2) Suppose that the symbol rate is 1 megasymbol per second and that the raised cosine has 50 percentexcess bandwidth. What is the passband absolute bandwidth?3) Suppose that the absolute bandwidth of a signal is 1MHz at baseband. What is the best symbolrate that can be achieved with a raised cosine pulse? Choose any raised cosine pulse rolloff factor(e.g., 0.2, 0.3...)4) Suppose that the absolute bandwidth of your modulated signal is 3MHz at baseband with an excessbandwidth of 25 percent. What is the Nyquist frequency? What is the Nyquist rate
