The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.

We all know that electric utilities in the United States generate electricity at various 60-Hz voltage levels that result in a sine wave waveform. The height, or amplitude, of this sine wave is called ...

In order to measure the RMS value of an alternating voltage an accurate converter is required to produce the true RMS value of its alternating input as a DC output. With simple sinewave inputs the RMS ...
