Vpwm
Purpose.............. to measure on pulse width modulated
signals, like motor drive inverter outputs
Principle ......readings show the effective voltage based
on the average value of samples over a
whole number of periods of the fundamental
frequency
Accuracy ......................... as Vrms for sinewave signals
