Parity Check Code

Simplest error detection code, adding 1 parity bit

Real-World Applications

Parity bits in computer RAM, UART serial communication (RS-232/485 industrial control). Although it can only detect odd number of errors, it is still widely used in low-error environments due to minimal overhead (only 1 bit).

Experiment Steps

Detection Capability: Can only detect odd number of errors

Simulation Experiment

Parity Check Principle Demo

Parity Check Demo (Even Parity)

Transmitter

Parity Bit = 0→Make even→P = 0

Receiver

Check: PASS→Check OK

Transmission correct, check passed ✅

Explanation: Parity check works by counting the number of '1's.
