Answer:
5KHz
Explanation:
The formula for calculating the output frequency when the input frequency and the number of flip-flops are given.
[tex]out put Frequency = \frac{in put frequency}{2^{N}}[/tex]
here, N is the number of filp-flops.
Note: The input frequency must be in Hz.
first convert given input frequency (MHz) into HZ.
[tex]in put frequency = 20.48 *10^{6}Hz[/tex]
apply the formula:
[tex]out put Frequency = \frac{20.48*10^{6}}{2^{12}}[/tex]
which comes out to be 5000Hz or 5KHz.
