En primer lugar, la función de la filtrar
Loop function: make the signal of a certain frequency band pass smoothly and filtrar out the signal of other frequency band, so it is actually a frequency selection loop. Filtrar is a very important loop in weak signal measurement, and analog filtrar is almost indispensable in various signal processing. The signal below is low pass filtrared.
Second, the role of the filtrar
1. Separe la señal útil y el ruido, mejore la señal anti-interferencia y la relación de ruido.
2. Filtrar uninteresting frequency components to improve analysis accuracy.
3. Separar los componentes de frecuencia única de los componentes de frecuencia complejos.
Mainly used to filtrar interference signals. Filtrars are often used to increase filtraring and before sampling signals while amplifying weak signals.
