If the input to T-flip flop is $100$ Hz signal, the final output of the three T-flip flops in cascade is :

  1. $1000$ Hz
  2. $500$ Hz
  3. $333$ Hz
  4. $12.5$ Hz

 The final output of the three T-flip-flops in cascade is

  (T) = Input Frequency / 2n          [ n is the number of flip flops ]

= 100 / 23

= 100 / 8

=12.5Hz

If the input to T-flip-flop is 100 Hz signal, the final output of the three T- flip-flops in cascade is 12.5 Hz

Which is Option D .

Both T and D Flip Flops, if given an input signal frequency, they divide it by 2. It's called Frequency Division.


Given a series of T flip flops, since they toggle the input, in their output is actually the bit shifted to the right by one position. This is equivalent to performing a right shift, which in turn is equivalent to $ ÷ 2$

Since here we have a series of 3 T Flip Flops, the original input frequency would be divided by 2 thrice.

=> $\frac{100}{2*2*2}$

Option D
