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. More... | |

Scramble an input stream using an LFSR.
This block works on the LSB only of the input data stream, i.e., on an "unpacked binary" stream, and produces the same format on its output.
