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
of merit Q= fr/ (fH- fL) = fr/B
where B= bandwidth.
types of filters are Narrow band pass and wide band pass filters
Wide band pass filter:
is connection of a low pass filter and a high pass filter in cascade.
fH of low pass filter and fL of high pass filter are
related as fH > fL
