Question

An AC signal of $50Hz$ frequency is input of a full wave rectifier using two diodes. The output frequency after full wave rectification is

• A. $25Hz$
• B. $50Hz$
• C. $100Hz$
• D. $200Hz$

Answer 1

Answer: (C)

$100Hz$

In full wave rectification the input frequency is doubled. Because all the negative components in the AC input signal are converted into positive components. Hence, the positive components are doubled.

Therefore in full wave rectification output frequency will be 100 Hz i.e. double that of input frequency 50 Hz.

Hence, option C is correct answer.
