ATSC BitTimingLoop3
This class accepts a single real input and produces two outputs, the raw symbol (float) and the tag (atsc_syminfo)

void atsc_bit_timing_loop::forecast | ( | int | noutput_items, |
gr_vector_int & | ninput_items_required | ||
) | [virtual] |
Estimate input requirements given output request.
noutput_items | number of output items to produce |
ninput_items_required | number of input items required on each input stream |
Given a request to product noutput_items
, estimate the number of data items required on each input stream. The estimate doesn't have to be exact, but should be close.
Reimplemented from gr_block.

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
noutput_items | number of output items to write on each output stream |
ninput_items | number of input items available on each input stream |
input_items | vector of pointers to the input items, one entry per input stream |
output_items | vector of pointers to the output items, one entry per output stream |
general_work must call consume or consume_each to indicate how many items were consumed on each input stream.
Implements gr_block.
