dc_block()

MAYAFLUX_API void MayaFlux::Kinesis::Discrete::dc_block	(	double	pole,
		std::vector< double > &	a,
		std::vector< double > &	b
	)

DC blocking filter.

A zero at DC with a pole just inside it, removing constant offset while leaving everything above the corner essentially untouched. The corner frequency falls as pole approaches 1.0.

Parameters

pole	Pole position, clamped to [0, 0.9999]; 0.995 is a typical value
a	Denominator output, resized to 2, a[0] == 1.0
b	Numerator output, resized to 2

    a.assign({ 1.0, -p });
    b.assign({ 1.0, -1.0 });
