The picture shows the practical differentiator circuit. The circuit consists of common operational amplifier. When the differentiator inputs a triangle wave, it outputs a square wave. The frequency of the input signal is decided by the resistor R1,R2 and the capacitor C. The circuit requires R1's resistance value to be 1/10 of R2's resistance value, that is: R1=R2/10. The capacitor C's capacitance value is determined by R2's value as well as the input frequency fin, and their relation is: C=1/R2fin. Similarly, if C's value is already known, then R's value can be got from the following formula: R2=1/Cfin.
