Galois LFSR pseudo-random source generating float outputs -1.0 - 1.0. Generates a maximal length sequence of length 2^degree-1.


Parameters

Degree
Degree of shift register must be in [1, 32]. If mask is 0, the degree determines a default mask (see digital_impl_glfsr.cc for the mapping).
Repeat
Set to repeat sequence.
Mask
Allows a user-defined bit mask for indexes of the shift register to feed back.
Seed
Initial setting for values in shift register.

Example Flowgraph

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
