Detailed Description
template<class T>
class HHumFilter< T >
Filter that removes or reduces mains hum by combining a comb filter with a lowpass filter in the feedback branch, which gradually reduces the filter effect. The result is a lowpass filter with extra notches at the mains frequency and harmonics. By giving the hum frequency and a cutoff frequency, you can adjust how aggressive the filter is and how far up the lowpass effect reaches.
- Examples
- saq.cpp.
