Discuss the below:
Q: Assume that a statistical multiplexer is used in the communications network described in Figure. There are 20 sources that transmit 20% of the time at rate of 32kbps.
a. Can this system work if the QPSK modulation is used and the media will support a baud/symbol rate of 40 kbps? Explain.
b. Can this system work if the baud/symbol rate is increased to 80kbps? Explain.
c. If Part b can be supported, what will be the buffer size of the multiplexer?
