Worksheet 23-Rectification

Question 1

Define rectification.

Answer 1

Rectification is a process where the negative polarity of an input signal is electrically filtered out.

Question 2

For an AC audio signal, why rectify the input?

Answer 2

If an audio signal is not rectified, the human ear would hear both the negative and positive peaks, which would cancel out the sound.

Question 3

What type of rectifier uses a single diode?

Answer 3

A single diode is called a half-wave rectifier.

Question 4

What type of rectifier is a bridge circuit?

Answer 4

A bridge rectifier is called a full-wave rectifier because the full wave conducts all of the time at the output.

Question 5

Using the space below, draw a diagram of a bridge rectifier and identify the input and output signals.

Answer 5

A bridge rectifier has 4 diodes drawn in a square. All of the diodes need to “point” in one direction. The input is connected directly across from the output.
