まず、 フィルター
Loop function: make the signal of a certain frequency band pass smoothly and フィルター out the signal of other frequency band, so it is actually a frequency selection loop. フィルター is a very important loop in weak signal measurement, and analog フィルター is almost indispensable in various signal processing. The signal below is low pass フィルターed.
Second, the role of the フィルター
1.有用な信号とノイズを分離し、信号の干渉防止とノイズ比を改善します。
2. フィルター uninteresting frequency components to improve analysis accuracy.
3. 複雑な周波数成分から単一の周波数成分を分離します。
Mainly used to フィルター interference signals. フィルターs are often used to increase フィルターing and before sampling signals while amplifying weak signals.
