Band pass filters using Operational Amplifier

Filters that pass band of frequencies and attenuates others.

Band pass filters

 

·           Filters that pass band of frequencies and attenuates others. Its high cutoff frequency and low cutoff frequency are related as fH >fL and maximum gain at resonant frequency

 

·           fr= √ fHfL

 

·           Figure of merit Q= fr/ (fH- fL) = fr/B where B= bandwidth.

 

·           2 types of filters are Narrow band pass and wide band pass filters

 

Wide band pass filter:

It is connection of a low pass filter and a high pass filter in cascade.

The fH of low pass filter and fL of high pass filter are related as fH > fL
