Question

In a half wave reitifier input frequency is 50 Hz. What is its output frequency? What is the out put frequency of a full wave rectifier for the same input frequency.

Answer 1

The frequency for half wave rectifier will be 50 Hz, same as input, while frequency of full wave rectifier will be 100 Hz, double than input.

Explanation:

If we look at the output signal when half wave rectifier is used, we will observe that the output wave repeats itself after the same interval as of input. But this is not the case with full wave rectifier. In full wave rectifier both parts of input are converted into output so, output wave repeats itself after half input cycle.
