Constructor & Destructor Documentation

Filter::Filter

(

Parameters

params

)

Construct an IIR filter with numerators b and denominators a.

The filter will have order b.size()-1. To make an FIR filter, leave the vector a in the param struct empty. Otherwise, a and b must have the same number of values.

void Filter::process	(	const double *const QM_R__	in,
		double *const QM_R__	out,
		const int	n
	)

Filter the input sequence.

• in of length
• n samples, and write the resulting
• n samples into
• out. There must be enough room in
• out for
• n samples to be written.
