Question

In a temperature control system, what conversion in signal takes place?

(a) Digital to Analog

(b) Analog to Digital

(c) Error to Digital

(d) Error to Analog

I have been asked this question in an international level competition.

I'd like to ask this question from Classification of Control Systems topic in section Control System and Components of Control Systems

Answer 1

The correct option is (b) Analog to Digital

To elaborate: In a temperature control system, analog to digital conversion of signals take place. Automatic systems don’t understand analog signals as they only take digital inputs in the form of 0 & 1 so we use a analog to digital converter which converts the signal.
