Detailed Description

Fast FFT filter with float input, float output and float taps.

Constructor & Destructor Documentation

gr::filter::kernel::fft_filter_fff::fft_filter_fff	(	int	decimation,
		const std::vector< float > &	taps,
		int	nthreads = `1`
	)

Construct an 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 complex vectors (such as fft_filter_ccc).

Parameters

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

gr::filter::kernel::fft_filter_fff::~fft_filter_fff ( )

int gr::filter::kernel::fft_filter_fff::filter	(	int	nitems,
		const float *	input,
		float *	output
	)

Perform the filter operation.

l *

Parameters

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

unsigned int gr::filter::kernel::fft_filter_fff::ntaps ( ) const

Returns the number of taps in the filter.

int gr::filter::kernel::fft_filter_fff::nthreads ( ) const

Get number of threads being used.

void gr::filter::kernel::fft_filter_fff::set_nthreads ( int n )

Set number of threads to use.

int gr::filter::kernel::fft_filter_fff::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 (complex)

std::vector<float> gr::filter::kernel::fft_filter_fff::taps ( ) const

Returns the taps.
