Member Function Documentation

int gr::filter::pfb_arb_resampler_fff_impl::general_work ( int  noutput_items,
gr_vector_int ninput_items,
gr_vector_const_void_star input_items,
gr_vector_void_star output_items 
)
virtual

compute output items from input items

Parameters
noutput_itemsnumber of output items to write on each output stream
ninput_itemsnumber of input items available on each input stream
input_itemsvector of pointers to the input items, one entry per input stream
output_itemsvector of pointers to the output items, one entry per output stream
Returns
number of items actually written to each output stream, or -1 on EOF. It is OK to return a value less than noutput_items. -1 <= return value <= noutput_items

general_work must call consume or consume_each to indicate how many items were consumed on each input stream.

Reimplemented from gr_block.

float gr::filter::pfb_arb_resampler_fff_impl::phase ( ) const
virtual

Gets the current phase of the resampler in radians (2 to 2pi).

Implements gr::filter::pfb_arb_resampler_fff.

void gr::filter::pfb_arb_resampler_fff_impl::print_taps ( )
virtual

Print all of the filterbank taps to screen.

Implements gr::filter::pfb_arb_resampler_fff.

void gr::filter::pfb_arb_resampler_fff_impl::set_phase ( float  ph)
virtual

Sets the current phase offset in radians (0 to 2pi).

Implements gr::filter::pfb_arb_resampler_fff.

void gr::filter::pfb_arb_resampler_fff_impl::set_rate ( float  rate)
virtual

Sets the resampling rate of the block.

Implements gr::filter::pfb_arb_resampler_fff.

void gr::filter::pfb_arb_resampler_fff_impl::set_taps ( const std::vector< float > &  taps)
virtual

Resets the filterbank's filter taps with the new prototype filter

Parameters
taps(vector/list of floats) The prototype filter to populate the filterbank.

Implements gr::filter::pfb_arb_resampler_fff.

std::vector<std::vector<float> > gr::filter::pfb_arb_resampler_fff_impl::taps ( ) const
virtual

Return a vector<vector<>> of the filterbank taps

Implements gr::filter::pfb_arb_resampler_fff.
