TheDCoutputsignalshouldreflectthermsvaluesoftheinputvoltage.
TheProblemsThealternatingvoltageswhichareusedarenotalwayssinusoidal,butsometimesdistorted.
ButtypicalAC/DCtransducersareonlydesignedforsinusoidalsources.
Withinputsignalswhicharenotsinusoidal,theyexhibit–sometimesconsiderable–errorsinformingthermsvalue,whichcanbesevereenoughtorenderthemea-surementvaluesunusable.
Thereforetruermsmeasurementisrequiredforsignalswhicharenon-sinusoidaland/oraredistorted.
