(a) In complex control systems

(b) Where high accuracy is required

(c) Non automated control systems

(d) Automated control system

I got this question in a job interview.

My query is from Signal Reconstruction topic in section Digital Control Systems of Control Systems

Answer 1

The correct option is (b) Where high accuracy is required

The best explanation: Sampling is the process where the continuous systems are converted into discrete time systems with the help of zero order hold of the signal and sampling is necessary where high accuracy is needed.
