Threshold

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.
