Unlike the low pass filter which only pass signals of a low frequency range or the high pass filter which pass signals of a higher frequency range, a Band Pass Filters passes signals within a certain “band” or “spread” of frequencies without distorting the input signal or introducing extra noise.

What is band pass and low pass?
A bandpass filter allows signals between two specific frequencies to pass, but that discriminates against signals at certain frequencies. A lopass filter is a filter that passes signals with a frequency lower than a certain cutoff frequency and minimizes signals with frequencies higher than the cutoff.
What do low pass high pass and band pass filters do?
A low-pass filter allows only signals at low frequencies through. A high pass filter allows only signals at higher frequencies to pass through. (A simple way to create a bandpass filter is to place a low pass and high pass filter in series.)
What is high band pass?
A high-pass filter (HPF) is an electronic filter that passes signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency.
