Integration involves finding the parentage of the function f(x) in traceable to an infinite. A comparator is an OP-Amp circuit without negative feedback and takes advantage of very high open-loop voltage gain. Thus output from second OP-Amp is given by: The gain of the second stage in the Subtractor can be varied to provide an output that is proportional to the difference between the input voltages. Any equation modelling the rate of change of one variable with respect to another variable is called as a differential equation. This change is so rapid that we get a square wave output for a sine wave input. A comparator has two input voltages and one output voltage. So, the three input currents I1, I2 and I3 combine at the summing point A and form the total current If which goes through Rf as shown in fig.1.
