Successively notches the fundamental and its first n_harmonics
harmonics. Each notch below Nyquist is applied; aliased harmonics
are skipped.
Usage
morie_dsp_comb(x, fundamental, fs, n_harmonics = 5L, q = 30)
Arguments
- x
Numeric vector.
- fundamental
Fundamental frequency (Hz), e.g. 60 for North
American mains.
- fs
Sampling frequency (Hz).
- n_harmonics
Number of harmonics to cancel. Default 5.
- q
Quality factor per notch. Default 30.
Value
Filtered vector, length(x).
