Question Set

1. A sequential multiplexer is connected as shown in figure. Each time the multiplexer receives the clock, it switches to the next channel from 6 to 1. If the input signals are : A = 10 cos 2p (4 x 103t) B = 15 cos 2p (5 x 103t) C = 20 cos 2p (6 x 103t) D = 10 cos 2p (10 x 103t) The minimum clock frequency should be __________ kHz.
