Circuit diagram of an example of differential and integral circuits

The differential and integral circuit diagram is shown below:

The differential circuit can convert a rectangular wave into a sharp pulse wave. The output waveform of the circuit only reflects the sudden change of the input waveform, that is, there is output only at the moment when the input waveform suddenly changes.

Differential circuits are mainly used in pulse circuits, analog computers and measuring instruments. They can obtain information contained in the leading and trailing edges of pulses, such as extracting time base standard signals.

Integral circuits are mainly used for waveform transformation, elimination of offset voltage in amplifier circuits, and integral compensation in feedback control.
