Good explanation about Differentiation

“The output wave of a DIFFERENTIATOR CIRCUIT is ideally a graph of the rate of change of the voltage at its input.”

——————————————————————————————–

“The shape of the input wave of an integrator circuit in this case will be a graph of the rate of change of the output wave ”

“The low pass filter circuit is therefore called an integrator only when:

a. The input wave is a square wave.

b. The periodic time(T) of the input wave is much shorter than the circuit time constant(CR) i.e.(T<=CR).”

See the image:

**Frequency = 1 / Tcycle **and Hertz is the unit of frequency. It gives the number of cycles in one second.

**Duty cycle = Thigh / Tcycle**. It gives fraction of one cycle for which the signal is high.
