First, the function of the filterLoop function: make the signal of a certain frequency band pass smoothly and filter out the signal of other frequency band, so it is actually a frequency selection loop. Filter is a very important loop in weak signal measurement, and analog filter is almost indispensable in various signal processing. The signal below is low pass filtered. Second, the role of the filter 1. Separate useful signal and noise, improve signal anti-interference and noise ratio. 2. Filter uninteresting frequency components to improve analysis accuracy. 3. Separate single frequency components from complex frequency components. Mainly used to filter interference signals. Filters are often used to increase filtering and before sampling signals while amplifying weak signals.
