Detailed Description

A set of Biquad filters in series.

Definition at line 13 of file lasp_biquadbank.h.

Constructor & Destructor Documentation

SeriesBiquad()

SeriesBiquad::SeriesBiquad

(

const vd &

filter_coefs

)

Initalize a SeriesBiquad filter.

Parameters

filter_coefs

Filter coefficients, should be given in the order as [b0, b1, b2, a0==1, a1, a2, b0,...]

Initialize state to zero

Check if third row in this matrix equals unity.

Member Function Documentation

clone()

std::unique_ptr< Filter > SeriesBiquad::clone ( ) const

finaloverridevirtual

Clone a filter, to generate a copy.

Returns

Copy of filter with state set to zero.

Implements Filter.

Definition at line 83 of file lasp_biquadbank.cpp.

filter()

void SeriesBiquad::filter ( vd &  inout )

finaloverridevirtual

Filter input, and provides output in same array as input.

Parameters

inout

Vector of input / output samples.

Implementation is based on Proakis & Manolakis - Digital Signal Processing, Fourth Edition, p. 550

Implements Filter.

Definition at line 91 of file lasp_biquadbank.cpp.

firstOrderHighPass()

SeriesBiquad SeriesBiquad::firstOrderHighPass ( const d  fs, const d  cuton_Hz  )

static

Create a SeriesBiquad object for a first order high-pass filter.

Parameters

fs	Sampling frequency [Hz]
cuton_Hz	Cuton-frequency [Hz]

Returns

SeriesBiquad object with a single biquad, corresponding to a first order high pass filter.

Definition at line 45 of file lasp_biquadbank.cpp.

reset()

void SeriesBiquad::reset ( )

finaloverridevirtual

Reset filter state to 0 (history was all-zero).

Implements Filter.

Definition at line 87 of file lasp_biquadbank.cpp.
