DIFFERENTIAL GAIN

Also known as anti-hunting gain or rate,

differential gain is really not a gain, but a time. Differential gain

is seldom used, but it helps to stop oscillations on slowly changing variables (temperature). Any high

frequency changes in the system variable (including noise, if present) are picked up by the differential

circuit and could lead to instability.

The longer the derivative time, the stronger the derivative action
