A communication system consists of blocks of the transmitter and the receiver of 4-bit messages. Messages represent 3-bit codes (B2, B1, B0) and parity bit P generated at the transmitter side for odd parity. The parity checker at the receiver asserts output E (E=1) if parity was changed. With no change of parity, output E=0. Obtain the following a) Truth tables for P and E.
b) Implement both the parity bit generator and the parity checker with XOR2 or XNOR2 gates. Show the schematics. The parity bit generator has 3 inputs and output P. The checker has 4 inputs and output E.
