Bandpass filter: A bandpass filter includes an LPF and a high pass. It permits only selectable frequency to pass and block the above and below frequencies. Cut off frequency of the LPF is higher in comparison with the cut off frequency of the high pass filter. Because of this, it allows only a specific range of frequency to pass.
Bandstop filter: Bandstop filter or notch filter is opposite to Bandpass filter as they block the specific range of frequency and allows the rest of frequency to pass through. It is reverse of the bandpass filter and can be designed simply using the same input at a high pass and an LPF.
