    In signal processing, a band-stop filter or band-rejection filter is a filter that passes most frequencies unaltered, but attenuates those in a specific range to very low levels. It is the opposite of a band-pass filter. A notch filter is a band-stop filter with a narrow stopband (high Q factor).

    on what parameters Q relies upon? and is it true that a notch filter is a limiting case of band stop filter?

    \[Q=\omega0/\beta \]

    where \[\omega0\] is the central frequency

    and beta is the band width

    band reject filter as the name suggests .. rejects a band and notch filter is used to select a particular frequency and nt a band
