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.
- 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.
