(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.
