Multiple choice

TO Marks 1. The Boolean function F-49) B @ , D--1 means. a all inputs are zeros (4 0,8-0, C-o.D 0) c. half of the inputs are zeros ( for example: A s 0,B-o.c: 1, D-1). d one or two or three of the inputs are ones. b all inputs are ones A1,BC1.D e one or three of the inputs are ones 2. Given F(, y,2) IM(O. 3, 4, 7) and G is the complement of F, then a G(x, y, z) 1n(0,3,4,7) e. G (x, y, :) Im (1.2, 5. 6) e, G (x,y,z). IIM (0, 1, 2, 3, 4, 5.6.7) b. Gu.y,a) IIM (0, 3,4, 7) d. G(u,ya 2m (0, 1,2,3,4,5,6,7) 3- Even parity is a. an extra bit added to make the total number of ones even to detect odd b. an extra bit added to make the total number of ones even to detect even number e. an extra bit added to make the total number of ones odd to detect odd number of errors d an estra bit added to make the total number of ones odd to detect even number e. an extra bit added to make the total number of ones even number of errors to detect any number of errors. 4. The shown eircuit: 12 D a. always produces F # 1. b. always produces F o. e. generates an odd parity, when used with 4-bit data. d generates an even parity, when used with 4-bit data. e checks for even parity errors, when used with 3-bit data and a parity (F-I means an error has occurred). S. For the shown cireuit, the Boolean function: x a. F x AND y b. F x NAND y
