Parameters

(R): Run-time adjustable

Audio rate

Sample rate of audio stream, >= 16k (integer)

Quadrature rate

Sample rate of output stream (integer). Must be an integer multiple of Audio rate.

Tau

Preemphasis time constant (float)

Max deviation (R)

Maximum deviation in Hz (float)

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.
