Add a parity bit next to the LSB of the following hexadecimal codes to form even parity.

Add a parity bit next to the LSB of the following hexadecimal codes to form even parity: 0111, 1101, 1010, 1111, 1000 000 1. 2. Design a system-called a parallel binary comparator-that compares the 4-bit binary string A to the 4-bit binary string B. If the strings are exactly equal, provide a HIGH-level output to drive a warning buzzer. Ag Binary A string Binary B string
