(d) Delta Sigma approximation

This question was addressed to me during a job interview.

Question is taken from Single Channel Data Acquisition System topic in division Data Acquisition System of Electrical Measurements

Answer 1

Correct option is (c) Successive approximation

To elaborate: The successive approximation technique is most widely used in a single channel data acquisition system. This is due to the fact that it has a high value of resolution and high speed.
