Comparison between analog voltmeter and digital voltmeter

Analog voltmeter Digital voltmeter
In analog voltmeter the output signal representation is done by using potentiometric deflection. In digital voltmeter the output signal is represented in the digital form.
The different type are:

  1. Average reading
  2. True rms reading
  3. Sampling type etc.
The different type are:

  1. Ramp type
  2. Integrated type
