The parity generator is a combinational logic circuit. To transmit this bitstream containing n-1 data (message signal) plus one additional parity bit, we require a special circuit known as parity bit generator. How does a Parity Generator work?Īssume that your final message is an n-bit stream of digital data. The Parity checker is present at the receiver end for error detection through parity bit count. Later it combines with the message signal. A parity generator is present at the transmitter end to generate the parity bit. On the other hand, a parity checker is a circuit that checks the parity (number of 1s) of the message signal.īoth these circuits are located at different sites based on their working. The primary difference between parity generator and a parity checker is that a parity generator is a combinational logic circuit we use in the generation of the parity bit. But for the sake of clarity, I’ll mention it. What is the difference between a Parity Generator and a Parity Checker? Next, we will design some good lookin’ circuits to carry out this whole process. And we can detect if an error is present. Cross-reference that with what we knew at the transmitting end. When the message reaches the destination, all we need to check is the parity bit if it is odd or even parity. Final message = Message signal + parity bit Notice one thing? In this error detection method, the final message is the message you intended to send, plus one parity bit.
