electronic voltmeter effective and block diagram electrical.
an analog electronic voltmeter uses an electronic amplifier to increase the do its stuff of an electromechanical voltmeter for example an electronic voltmeter has a much higher input resistance than an electromechanical instrument so voltmeter loading effect is considerably reduced.
digital voltmeters dvm s functional working principle block diagram.
working principle of digital voltmeters from the above block diagram t he voltage to be measured is given to the input signal spread around in the circuit diagram and next-door to this signal is processed onto the pulse generator which generates a train of rectangular pulses by using both analog and digital techniques.
