Narrow Band Pass Filter Circuit Diagram. This filter circuit produces narrow band pass filter response. The ideal characteristics of the band pass filter are as shown below.
A sample circuit diagram of a simple passive bandpass filter is shown below. Narrow bank reject filter notch filter step 1. Generally the narrow bandpass filter is designed for specific values of centre frequency f c and q or f c and bw.
It is a combination of the high pass filter and low pass filter.
This shows that the op amp is in inverting configuration. C1 c2 c. The voltage gain of the above filter circuit is a v r 2 r 1 the cut off frequencies of the filter circuit are. The main features of this filter mainly include the following.
