The function of a filter - a bandpass filter
Sep 06, 2018

For bandpass filter, it allows the signal of a certain frequency band to pass. This frequency band is different from the low-frequency signal of low-pass filter and the high-frequency signal of high-pass filter. It is a signal of a certain frequency band in the middle, and it can suppress the signal, interference and noise of a lower or higher frequency band. Equivalent to a high - pass and low - pass series, the high and low are filtered, leaving a middle frequency band.
