Bandpass filter allows signals within a specific range of frequencies, called the passband, to pass through while attenuating signals outside this range.
RC high pass filter, RL high pass filter, Equalisation, low frequency rejection, AC coupling.
RC low pass filter, RL low pass filter, Treble cut filter, High-frequency rejection, anti-aliasing filter.
An analog filter is a circuit that selectively allows certain frequencies to pass through while attenuating others. These are made using resistors, capacitors, inductors, transistors, and opamps.
