QUESTION:
(a) For the bit stream 010011, sketch the waveforms for each of the code indicated. Assume that the signal level for a space in NRZ-L is positive; the signal level for the previous mark for NRZI was positive; the most recent preceding mark for AMI was negative; and the most recent preceding space for pseudoternary was negative.
(b) Assume that you want to fully protect the ASCII character "K" with odd-parity during transmission using a Hamming Code scheme. Assume the parity bit is inserted as the MSB. Calculate the transmitted codeword.
(c) Draw the waveform for an asynchronous transmission with the following specifications:
8 data bits with value 11010001 (LSB listed first here), one parity bit (even), one start bit, one stop bit, and a baud rate of 4800. Then, assuming the transmission begins at time t = 0, label the starting/ending time for each bit in the transmission.
