Rectifiers & Filters

The frequency of a given a.c. signal is 'N' Hz. When it is connected to a half wave rectifier, the number of output pulses given by the rectifier in 1 second is

Show answer and solution

Answer: (c)

A half-wave rectifier passes only one half of each cycle, giving one output pulse per cycle.
In 1 s there are $N$ cycles, so there are $N$ pulses.
So the answer is (c) N.
