sah
Sample and hold operator (Schmitt trigger)
Description
Use sah to capture ("sample") and continually output ("hold") the value of an input number whenever another "control" value rises above a specified threshold. The sampled value is "held" until the control number value drops below and then rises above the threshold value once more at which point the input is sampled again.
Inlets
input [number]
The input value value that is sampled or held.
trig [number]
The trigger vale. When the trigger is above the threshold , the input is held and when it drops below the threshold, the input is sampled again.
thresh [number]
The threshold that the trigger must pass to switch between sample and hold behaviors.
Dynamic Attributes
These attributes can be modified in the code during execution using the set object
input [number]
The input value value that is sampled or held.
thresh [number]
The threshold that the trigger must pass to switch between sample and hold behaviors.
trig [number]
The trigger vale. When the trigger is above the threshold , the input is held and when it drops below the threshold, the input is sampled again.
