int | fixed_rate_ninput_to_noutput (int ninput) |
Given ninput samples, return number of output samples that will be produced. N.B. this is only defined if fixed_rate returns true. Generally speaking, you don't need to override this. | |

Given noutput samples, return number of input samples required to produce noutput. N.B. this is only defined if fixed_rate returns true. Generally speaking, you don't need to override this. |

Convert stream of bytes to stream of +/- 1 symbols
input: stream of bytes; output: stream of float.
This block is deprecated.
The combination of gr_packed_to_unpacked_bb followed by gr_chunks_to_symbols_bf or gr_chunks_to_symbols_bc handles the general case of mapping from a stream of bytes into arbitrary float or complex symbols.
