Detailed Description

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.
