A low-pass filter allows low-frequency signals to pass through while attenuating high-frequency signals. A high-pass filter does the opposite, allowing high-frequency signals to pass through while attenuating low-frequency signals. When these two filters are connected in parallel, they form a band-pass filter, which allows a range of frequencies to pass through while attenuating frequencies outside that range.
