Output of T-flip flop is square wave. If input clock frequency is 20KHz, what is the frequency of the output of T-FF

To determine the frequency of the output of a T-flip flop, we need to understand how it works.

A T-flip flop is a type of flip flop that toggles its output based on the input T (toggle) signal and the clock signal. When the clock signal transitions from low to high (rising edge), the T-flip flop checks the value of the T input. If the T input is high, the output toggles (changes from low to high or high to low). If the T input is low, the output remains the same.

In this case, the input clock frequency is given as 20KHz. This means that the clock signal transitions from low to high 20,000 times per second.

Since the T-flip flop toggles its output on each rising edge of the clock signal, the frequency of the output will be half of the input clock frequency. Therefore, the frequency of the output of the T-flip flop in this case would be 10KHz.
