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)
- High 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.
