What is a Digital Voltmeter? Block diagram, working, types and.. The figure below shows the block diagram of a typical digital voltmeter. As we can see, the block diagram consists of attenuator with an analogue to digital converter after it. This ADC unit basically distinguishes between various types of Digital Voltmeters which we will discuss later. A counter section is also employed in the circuitry that is usually a decade counter. The read-out system is used to display the digital voltage of the input signal.
Web A digital voltmeter consists of analog to digital converter, a signal processing and a digital display. The figure 1 shows the block diagram of a DVM. Working of Digital Voltmeter..
