The second-order Butterworth filter consists of two reactive components. The circuit diagram of a second-order low pass Butterworth filter is as shown in the below figure. Second-order Low Pass Butterworth Filter In this type of filter, resistor R and RF are the negative feedback of op-amp....
Second-order filters are important because higher-order filters are designed using them. The gain of the second-order filter is set by R1 and RF, while the cutoff frequencyfHis determined by R2, R3, C2& C3values. The derivation for the cutoff frequency is given as follows, fH= 1 ...
