Question

What is the output frequency for a counter circuit that contains 12 flip-flops with an input clock frequency of 20.48 MHz?

Answer 1

5KHz

Step-by-step explanation:

The formula for calculating the output frequency when the input frequency and the number of flip-flops are given.

`out put Frequency = (in put frequency)/(2^(N))`

here, N is the number of filp-flops.

Note: The input frequency must be in Hz.

first convert given input frequency (MHz) into HZ.

`in put frequency = 20.48 *10^(6)Hz`

apply the formula:

`out put Frequency = (20.48*10^(6))/(2^(12))`

which comes out to be 5000Hz or 5KHz.
