If the input to T-flipflop is 200 Hz signal, the final output of the t...
Explanation:
The T-flipflop is a type of flipflop that toggles its output based on the input signal. It has two inputs: T (toggle) and CLK (clock) and one output Q.
Given:
Input signal frequency = 200 Hz
Working:
When a T-flipflop receives a pulse at its CLK input, it toggles its output (Q) based on the value of the T input. If T = 0, the output remains the same, and if T = 1, the output flips.
In a cascade connection of three T-flipflops, the output of one flipflop is connected to the CLK input of the next flipflop. This means that the output of the first flipflop becomes the input to the second flipflop, and so on.
Since the input signal to the first T-flipflop is a 200 Hz signal, the output of this flipflop will toggle at 200 Hz. This means that the output will change its state (from 0 to 1 or from 1 to 0) 200 times per second.
Now, the output of the first flipflop becomes the input to the second flipflop. Since the output of the first flipflop toggles at 200 Hz, the input to the second flipflop will also toggle at the same frequency.
Similarly, the output of the second flipflop becomes the input to the third flipflop. So, the input to the third flipflop will also toggle at 200 Hz.
Therefore, the final output of the three T-flipflops in cascade will also toggle at 200 Hz.
Conclusion:
The final output of the three T-flipflops in cascade is 200 Hz.
Therefore, the correct answer is option 'A' (25 Hz).

If we pass the input signal to a single T-flip flop, we will get half of the frequency at the output.
Similarly, when we pass the input signal into an n-bit flip flop counter, the output frequency (fout) will be:
Given Input frequency f = 200 Hz
fout = 25 Hz
