Question
In half-wave rectification, what is the output frequency if the input frequency is 50 Hz. What is the output frequency of a full-wave rectifier for the same input frequency.
Solution
Given,
Input frequency for half-wave and full-wave rectifier = 50 Hz.
Input and output waveforms of half-wave and full-wave rectifier are shown in figures (a) and (b).
During a cycle, half-wave rectifier conducts once and
full-wave rectifier conducts twice.
Therefore, output frequency for half-wave and full-wave rectifier are 50 Hz and 100 Hz respectively.
Input frequency for half-wave and full-wave rectifier = 50 Hz.
Input and output waveforms of half-wave and full-wave rectifier are shown in figures (a) and (b).

During a cycle, half-wave rectifier conducts once and
full-wave rectifier conducts twice.
Therefore, output frequency for half-wave and full-wave rectifier are 50 Hz and 100 Hz respectively.
