What is the output frequency of both a full wave rectifier and a bridge rectifier?

A full wave rectifier and a bridge rectifier both take an alternating current (AC) input and convert it into direct current (DC). The key function of these rectifiers is to utilize both halves of the AC waveform, which is what distinguishes them from half-wave rectifiers.

The input frequency is the frequency of the AC supply, typically measured in hertz (Hz). When the AC input is passed through a full wave or bridge rectifier, the rectifiers allow both the positive and negative halves of the AC wave to contribute to the output. This means that the output wave is effectively made up of both half-cycles of the input wave.

As a result of processing both halves of the waveform, the output frequency of a full wave or bridge rectifier is double that of the input frequency. Specifically, for every complete cycle of the AC input, there are two pulses in the output — one for each half of the input waveform. Hence, the correct assertion is that the output frequency is twice the input frequency.

Understanding this concept is crucial for designing circuits that require specific frequency characteristics when converting AC to DC.
