Functional Description:

The Pulse-Width Modulation operator generates a pulse-train waveform (alternating between LOW and HIGH) output with variable period and duty-cycle. One period or cycle of the waveform consists of a single interval of HIGH output followed by a single interval of LOW output. The period input P, determines the duration (in seconds) of one output cycle. The duty cycle input DC determines the percentage of the period that the output remains HIGH. For example, if the inputs are fixed at P=10 seconds and DC=30%, the output waveform will be HIGH for three seconds and LOW for seven seconds.

Reset input R restarts the waveform cycle.

User-Defined Properties:

Object Name. A string label that identifies the operator

Comments:

If the duty cycle input is set to 0%, the output will be LOW throughout the entire cycle.
If the duty cycle input is set to 100%, the output will be HIGH throughout the entire cycle.
