Output a 1 or zero based on a threshold value.
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.
Test the incoming signal against a threshold. If the signal
excedes the High value, it will change its output to 1, and if the signal
falls below the Low value, it will change its output to 0.

Output a 1 or zero based on a threshold value.

Test the incoming signal against a threshold. If the signal excedes the High value, it will change its output to 1, and if the signal falls below the Low value, it will change its output to 0.

Parameters

(R): Run-time adjustable

Low (R)
Low threshold. Outputs 0 if input goes below it
High (R)
Low threshold. Outputs 1 if input goes above it
Initial value
Value to output before the input reach one of the thresholds. Can be any value, not just 0 or 1.

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.
