Constructor & Destructor Documentation

gri_fft_filter_fff_generic::gri_fft_filter_fff_generic	(	int	decimation,
		const std::vector< float > &	taps,
		int	nthreads = 1
	)

Construct a FFT filter for float vectors with the given taps and decimation rate.

This is the basic implementation for performing FFT filter for fast convolution in other blocks for floating point vectors (such as gr_fft_filter_fff).

Parameters:

decimation	The decimation rate of the filter (int)
taps	The filter taps (float)
nthreads	The number of threads for the FFT to use (int)

Member Function Documentation

int gri_fft_filter_fff_generic::filter	(	int	nitems,
		const float *	input,
		float *	output
	)

Perform the filter operation.

Parameters:

nitems	The number of items to produce
input	The input vector to be filtered
output	The result of the filter operation

int gri_fft_filter_fff_generic::nthreads

(

)

const

Get number of threads being used.

void gri_fft_filter_fff_generic::set_nthreads

(

int

n

)

Set number of threads to use.

int gri_fft_filter_fff_generic::set_taps

(

const std::vector< float > &

taps

)

Set new taps for the filter.

Sets new taps and resets the class properties to handle different sizes

Parameters:

taps	The filter taps (float)
