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 necessary.  Note 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.

Gate, or zero output if CTCSS tone not present

Parameters

(R): Run-time adjustable

Sampling Rate
sample rate (Hz)
Tone Frequency (R)
Frequency value to use as the squelch tone (default: 100.0)
Level (R)
threshold level for the squelch tone (default: 0.01)
Length
length of the frequency filters (default: 0)
Ramp
Attack / release time in samples; a sinusodial ramp is used. set to 0 to disable (default: 0)
Gate
if true, no output if no squelch tone. if false, output 0's if no squelch tone (default: False)

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.
