True RMS Reading Voltmeter

True RMS Reading VoltmeterThe scale of general voltmeters (average reading voltmeters) is calibrated in terms of the RMS value of sinusoidal waveform only. So to read the RMS value of any waveform we use True RMS Reading Voltmeter.In this The input signal is amplified by an AC amplifier and then the...
