What is a peak detector circuit?

Definition: Peak detector circuits are used to determine the peak (maximum) value of an input signal. It stores the peak value of input voltages for infinite time duration until it comes to reset condition. The peak detector circuit utilizes its property of following the highest value of an input signal and storing it.

How to design peak detector circuit?

A basic peak detector circuit is a connection of a diode and a capacitor in series. In our circuit, we are giving a sine wave input from a 220v to 6v step-down transformer. The diode is placed in forward biased condition and for output, the oscilloscope probe is connected between the diode and capacitor.

What is a detection circuit?

In radio, a detector is a device or circuit that extracts information from a modulated radio frequency current or voltage. The term dates from the first three decades of radio (1888-1918).

What is basic difference between peak detector and AC voltmeter?

Explanation: A conventional ac voltmeter is designed to measure rms value of the pure sine wave whereas, the peak value of the non-sinusoidal wave forms can be a peak detector. 5.
