Question

In continuous data systems:

(a) Data may be continuous function of time at all points in the system

(b) Data is necessarily a continuous function of time at all points in the system

(c) Data is continuous at the inputs and output parts of the system but not necessarily during intermediate processing of the data

(d) Only the reference signal is continuous function of time

I have been asked this question in an online quiz.

The above asked question is from Transfer Functions topic in portion Mathematical Models of Physical Systems of Control Systems

Answer 1

Right option is (b) Data is necessarily a continuous function of time at all points in the system

To elaborate: Continuous signals are the signals having values for the continuous time and if impulse response decays to zero as time approaches infinity, the system is stable.
