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.

This is a convenience wrapper for calling firdes.root_raised_cosine(). A root-raised-cosine (RRC) filter is one of the most common pulse shaping filters in digital communications systems, used to perform matched filtering. See [https://en.wikipedia.org/wiki/Root-raised-cosine_filter for more info on RRC filtering.

Parameters

Gain
Scaling factor applied to output.
Sample Rate
Input sample rate in Hz.
Symbol Rate
Input symbol rate in Hz, NOT samples per symbol.
Excess BW
The filter parameter, sometimes called roll-off factor or beta, between 0 and 1. A higher value means more bandwidth is being used. A common value is 0.35.
Num Taps
Number of taps for the generated filter to have
