A BCD code is being transmitted to a remote receiver. The bits are A3,A2,A1 and A0 as the least significant digits. The receiver circuitry include a BCD error detector circuit that examines the receivers code to check if it is a legal BCD code. Design the error detector

Respuesta :

3-bit message with A3 as an EVEN parity bit
A3 = ((A0 xor A1) xor A2)
