(a) Draw the waveform for an asynchronous transmission with the given specifications:
8 data bits with value 11010001 (LSB listed first here), one parity bit (even), one start bit, one stop bit, and a bit rate of 4800 bps. Then, assuming the transmission starts at time t = 0 with idle being HIGH, label the starting/ending time for each bit in the transmission.
(b)Provide eight advantages that digital technology has over analog technology in terms of data communication.
(c) Explain three kinds of communication impairments that you are familiar with and, for every type, mention how their undesirable effects can be reduced.
(d) Give two advantages and two disadvantages of fibre optics (FO) cabling compared to twisted-pair (TP) cabling.
