Alogic circuit realizing the function f has four inputs a, b, c, d. the three inputs a, b, and c are the binary representation of the digits 0 through 7 with a being the most significant bit. the input d is an odd-parity bit; that is, the value of d is such that a, b, c, and d always contains an odd number of 1’s. (for example, the digit 1 is represented by abc = 001 and d = 0, and the digit 3 is represented by abcd = 0111.) the function f has value 1 if the input digit is a prime number. (a number is prime if it is divisible only by itself and 1; 1 is considered to be prime, and 0 is not.)
