Zunächst die Funktion der Filter
Loop 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. Nutzsignal und Rauschen trennen, Signalentstörung und Rauschabstand verbessern.
2. Filtern Sie uninteressante Frequenzkomponenten, um die Analysegenauigkeit zu verbessern.
3. Trenne einzelne Frequenzkomponenten von komplexen Frequenzkomponenten.
Mainly used to Filter interference signals. Filters are often used to increase Filtering and before sampling signals while amplifying weak signals.
