Study Notes
Parity Generator Circuit
- Typically, one parity bit is added to a data word in a simple parity generator.
- The primary function of a parity generator circuit is to add a parity bit to the data word.
Parity Bit Calculation
- In a parity generator circuit, the XOR gate plays a crucial role in calculating the parity bit.
- The XOR gate is used to perform a modulo-2 addition of the data bits to calculate the parity bit.
Parity Bit Purpose
- The purpose of a parity bit in data transmission is to detect single-bit errors that may occur during data transmission.
- The parity bit is used as an error-detection mechanism to ensure data integrity.
Even Parity Calculation
- In a parity generator circuit, the parity bit for even parity is calculated by performing a modulo-2 addition of the data bits using an XOR gate.
- The result of the modulo-2 addition determines the value of the parity bit, which is set to 0 for even parity or 1 for odd parity.
