CheckPwmSignal

ID: Check/CheckPwmSignal

Analyse a PWM signal - Check the period and the duty cylce.

Note: A period starts with a rising edge and ends at the next rising edge. The duty cylce is the duration from the rising to the falling edge divided by the period. With the CheckCondition, it is possible to select the interval to check. If an interval is active the evaluation starts at the next rising edge.
