먼저, 의 기능 필터
Loop function: make the signal of a certain frequency band pass smoothly and 필터 out the signal of other frequency band, so it is actually a frequency selection loop. 필터 is a very important loop in weak signal measurement, and analog 필터 is almost indispensable in various signal processing. The signal below is low pass 필터ed.
Second, the role of the 필터
1. 유용한 신호와 잡음을 분리하고 신호 간섭 방지 및 잡음 비율을 향상시킵니다.
2. 필터 uninteresting frequency components to improve analysis accuracy.
3. 단일 주파수 구성요소를 복잡한 주파수 구성요소에서 분리합니다.
Mainly used to 필터 interference signals. 필터s are often used to increase 필터ing and before sampling signals while amplifying weak signals.
