Question
Output of T-flip flop is square wave. If input clock frequency is 20KHz, what is the frequency of the output of T-FF?
a. 40KHz
b. 10KHz
c. 5KHz
d. 20KHz
Solution
To determine the frequency of the output of a T-flip flop, we need to understand its behavior. A T-flip flop toggles its output state (from 0 to 1 or from 1 to 0) whenever the clock input transitions from low to high (rising edge) or from high to low (falling edge).
In this case, the input clock frequency is given as 20KHz. This means that the clock signal transitions from low to high (or high to low) 20,000 times per second.
Since the T-flip flop toggles its output state with each clock transition, the frequency of the output will be twice the frequency of the input clock. Therefore, the frequency of the output of the T-flip flop in this case would be 40KHz.
So, the correct answer is option a. 40KHz.
