Question

A successive approximation type DVM makes use _______

(a) of a digital divider

(b) of an analog divider

(c) of an oscillator

(d) of a transducer

This question was addressed to me in examination.

This key question is from Successive Approximation Type DVM topic in section Electronic Instruments of Electrical Measurements

Answer 1

The correct option is (a) of a digital divider

The explanation: Servo balancing type DVM makes use of a linear divider in a potentiometer. In the case of a successive approximation type DVM we make use of a digital divider. A digital divider is basically a digital to analog converter.
