Assignment:
Digital radio transmission requires the use of a carrier wave which is modulated by the digital data.
a. What are the three possible ways in which a radio frequency carrier can be modulated to carry digital data?
b. Write down the equation for the occupied bandwidth of a digital band pass (radio) link that has ideal RRC filters with alpha = 0.4 and a symbol rate Rs sps.
c. A digital radio link uses BPSK modulation and has a bit rate of 38.4 kbps. If the transmitter and receiver have ideal RRC filters with alpha = 0.4, what is the bandwidth occupied by the RF signal?
d. What is the RF bandwidth required by the radio link specified in part (c) above?
Provide complete and step by step solution for the question and show calculations and use formulas.
