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 RRC filter at wikipedia] for more info on RRC filtering.

This is the template for the [[:Category:Block_Docs|"Page-per-block Docs"]]. This first section should describe what the block does and how to use it, using however many paragraphs necessaryNote that the title of the wiki page should match the block's name in GRC, i.e. the one defined in the block's .grc file. Look at the [[FFT]] Block for a good example.
 
As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.


== Parameters ==
== Parameters ==
; Gain
(''R''): <span class="plainlinks">[https://wiki.gnuradio.org/index.php/GNURadioCompanion#Variable_Controls ''Run-time adjustable'']</span>
: Overall gain of filter (default 1.0)
 
; Sample Rate
: Sample rate in samples per second.
 
; Symbol Rate
: Symbol rate, must be a factor of sample rate. Typically ((samples/second) / (samples/symbol)).


; Excess BW
; Param 1 (''R'')
: Excess bandwidth factor, also known as alpha. (default: 0.35)
: Description of parameter, provide any tips or recommended values. Note that the name of the parameter above should match the param's label that shows up in grc (e.g. Sample Rate).


; Num Taps
; Param 2
: Number of taps (default: 11*samp_rate)
: blah blah blah

This flowgraph can be found at [https://github.com/gnuradio/gnuradio/blob/master/gr-filter/examples/filter_taps.grc].
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.
