Practical differentiator

Other Circuits
Differentiating circuit as shown for the utility. The op amp circuit constituted by Universal. When the differential input a triangular wave, square wave output, while the inpu

t signal frequency by the circuit resistors R1, R2 and capacitor C decision. The circuit requires about one-tenth of the value of R1 R2, namely:R1 R2/10 The value of the capacitor C is jointly determined by the R2 value of the input frequency fin, their relationship: C 1/R2fin Similarly, if the known value C, then R. Values calculated by the following formula:R2 1/Cfin
