Detailed Description

FIR with internal buffer for gr_complex input, gr_complex output and gr_complex taps.

Constructor & Destructor Documentation

◆ fir_filter_with_buffer_ccc() [1/3]

gr::filter::kernel::fir_filter_with_buffer_ccc::fir_filter_with_buffer_ccc ( const std::vector< gr_complex > & taps )

construct new FIR with given taps.

Note that taps must be in forward order, e.g., coefficient 0 is stored in new_taps[0], coefficient 1 is stored in new_taps[1], etc.

Member Function Documentation

◆ filter() [1/2]

gr_complex gr::filter::kernel::fir_filter_with_buffer_ccc::filter	(	const gr_complex	input[],
		unsigned long	dec
	)

compute a single output value; designed for decimating filters.

input is a single input value of the filter type. The value of dec is the decimating value of the filter, so input[] must have dec valid values. The filter pushes dec number of items onto the circ. buffer before computing a single output.

Returns: the filtered input value.

◆ filter() [2/2]

gr_complex gr::filter::kernel::fir_filter_with_buffer_ccc::filter ( gr_complex input )

compute a single output value.

input is a single input value of the filter type

Returns: the filtered input value.

◆ filterN()

void gr::filter::kernel::fir_filter_with_buffer_ccc::filterN	(	gr_complex	output[],
		const gr_complex	input[],
		unsigned long	n
	)

compute an array of N output values.

input must have (n - 1 + ntaps()) valid entries. input[0] .. input[n - 1 + ntaps() - 1] are referenced to compute the output values.

◆ filterNdec()

void gr::filter::kernel::fir_filter_with_buffer_ccc::filterNdec	(	gr_complex	output[],
		const gr_complex	input[],
		unsigned long	n,
		unsigned long	decimate
	)

compute an array of N output values, decimating the input

input must have (decimate * (n - 1) + ntaps()) valid entries. input[0] .. input[decimate * (n - 1) + ntaps() - 1] are referenced to compute the output values.

◆ ntaps()

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

inline

Returns: number of taps in filter.

◆ operator=() [1/2]

fir_filter_with_buffer_ccc& gr::filter::kernel::fir_filter_with_buffer_ccc::operator= ( const fir_filter_with_buffer_ccc & )

delete

◆ operator=() [2/2]

fir_filter_with_buffer_ccc& gr::filter::kernel::fir_filter_with_buffer_ccc::operator= ( fir_filter_with_buffer_ccc && )

default

◆ set_taps()

void gr::filter::kernel::fir_filter_with_buffer_ccc::set_taps ( const std::vector< gr_complex > & taps )

install new_taps as the current taps.

◆ taps()

std::vector<gr_complex> gr::filter::kernel::fir_filter_with_buffer_ccc::taps ( ) const

Returns: current taps
