N-PATH FREQUENCY-TRACKING FILTER |
摘要 |
In a switching follower filter of the narrow-band-pass type having n switched paths for filtering a signal having a useful component of variable frequency associated with a high background noise, the fundamental frequency of the input signal is captured and then followed by collecting a pre-filtered switching synchronization signal so that part of the input signal remains in the pre-filtered signal. |
