... IN Figure 3. Single Supply Connection CHOOSING THE AVERAGING TIME CONSTANT The AD536A will compute the rms of both ac and dc signals. If the input is a slowly-varying dc signal, the output of the AD536A will track the input exactly. At higher frequencies, the average output of the AD536A will approach the rms value of the input signal ...

... For example, a rectangular pulse train with a 1% duty cycle has a crest factor η ). Figure curve of reading error for the AD536A for a 1 volt rms input signal with crest factors from 1 to 11. A rectangular pulse train (pulsewidth 100 µs) was used for this test since it is the worst-case waveform for rms measurement (all the energy is contained in the peaks) ...
