Question

Determine the output frequency for a frequency division circuit that contains 12 flip-flops with an input clock frequency of 20.48 mhz.

Answer 1

Answer:

Determine the output frequency for a frequency division circuit that contains 12 flip–flops with an input clock frequency of 20.48 MHz: 5 kHz

hope you get it....

Answer 2

The output frequency is 5 kHz.

Explanation:

Given that,

Number of flip flops = 12

Input clock frequency = 20.48 m Hz

$\text{12 flip flop} =2^{12}$

$\text{12 flip flop} =4096$

$\text{In-put clock frequency}=20.48\times10^{6}$

$\text{In-put clock frequency}=20480000$

We need to calculate the output frequency

Using formula of out put frequency

$\text{out-put frequency}=\dfrac{\text{in-put frequency}}{\text{12 flip flops}}$

Put the value into the formula

$\text{out-put frequency}=\dfrac{20480000}{4096}$

$\text{out-put frequency}=5000$

$\text{out-put frequency}=5\ kHz$

Hence, The output frequency is 5 kHz.
