fillKaiserSinc() [1/2]

template<class Data >

void signalsmith::rates::fillKaiserSinc	(	Data &&	data,
		int	length,
		double	centreFreq
	)

If only the centre frequency is specified, a heuristic is used to balance ripples and transition width.

The transition width is set to: 0.9/sqrt(length)

fillKaiserSinc() [2/2]

template<class Data >

void signalsmith::rates::fillKaiserSinc	(	Data &&	data,
		int	length,
		double	passFreq,
		double	stopFreq
	)

Fills a container with a Kaiser-windowed sinc for an FIR lowpass.

33-point results for various pass/stop frequencies
