A 4-bit binary up counter has an input clock frequency of 20 kHz. The frequency of the most significant bit is ________.-A-1.25 kHzB-2.50 kHzC-160 kHzD-320 kHz-A-1.25 kHz

Question

APTITUDE CRACK · Accepted Answer

A 1.25 kHz As it is a 4 bit up counter, requires 4 Flip Flops. Each Flip Flop divides the input frequency by 2. ie. f/2, f/4, f/8, f/16. So Output frequency = input frequency/16, Output frequency = 20 KHz/16, Output frequency = 1.25 KHz.
