ABSTRACT:
The measuring device of the rms value of a signal comprises, in series, a full-wave rectifier, a low-pass filter, for example of the RC type, and a peak detector. The output signal of the device is representative of the rms value of the input signal, the cut-off frequency of the filter corresponding to an angular frequency comprised between 4.pi.f/6 and 4.pi.f/5.33, f being the fundamental frequency of the input signal of the device.
