Please offer a brief justification for your answer to each of the following questions. The alternating-bit protocol and the SR protocol are interchangeable when the window sizes of the transmitter and receiver are both one.

Problem Five Consider a serial port operating with a baud rate of 10,000 bits per second. Draw the waveform occurring at the UOTX output (voltage levels are +3.3 and 0) when the ASCII 'a' (0x61) is transmitted on UARTO. The protocol is I start, 8 data and 1 stop bit. UARTO is initially idle, and the software writes the Ox61 to UARTO DR R at time=0. Show the UOTx line before and after the frame, assuming the channel is idle before and after the frame.

True or false, and explain your answer to the following questions briefly: The alternating-bit protocol is identical to the SR protocol when the transmitter and receiver window sizes are both 1.

What exactly is the difference between multiplexing and demultiplexing?
