sinc_lowpass()

MAYAFLUX_API std::vector< double > MayaFlux::Kinesis::Discrete::sinc_lowpass	(	double	frequency,
		double	sample_rate,
		size_t	taps
	)

Windowed-sinc lowpass FIR coefficients.

Truncates the ideal lowpass impulse response to taps and applies a Hann taper. Transition width narrows as taps increases; stopband attenuation is set by the taper, not the length.

Returned in FIR tap order: index 0 multiplies the newest sample. Group delay is (taps - 1) / 2 samples.

Parameters

frequency	Cutoff in Hz, clamped to (0, sample_rate/2)
sample_rate	Sampling rate in Hz
taps	Kernel length; odd values give an integer group delay

Returns

Coefficient vector of length taps
