Question
The following is a string of ASCII characters whose bitpatterns have been converted into hexadecimal for compactness: 73F4 E5 76 E5 76 E5 4A EF 62 73. Of the eight bits in each pair ofdigits, the leftmost is a parity bit. The remaining bits are theASCII code.(a) Convert the string to bit form and decode the ASCII
(b) Determine the parity used: odd or even?
