Determine the output frequency for a frequency division circuit that contains 12 flip-flops with an input clock frequency of 20.48 MHz.(a) 10.24 kHz(b) 5 kHz(c) 30.24 kHz(d) 15 kHzI have been asked this question in homework.This is a very interesting question from Flip Flops topic in chapter Flip-Flops of Digital Circuits

Answer»

Correct answer is (b) 5 KHZ

For explanation: 12 flip flops = 2^12 = 4096

Input CLOCK FREQUENCY =20.48*10^6 = 20480000

Output Clock frequency = 20480000/4096 = 5000 i.e., 5 kHz.
