Question

The standard test signal can be applied to give output to:

(a) Linear systems

(b) Non-linear systems

(c) Time variant systems

(d) Time invariant systems

This question was posed to me by my school teacher while I was bunking the class.

Query is from Necessary Conditions for Stability and Non-Linear Systems in division Stability and Algebraic Criteria of Control Systems

Answer 1

Right option is (a) Linear systems

For explanation I would say: For linear systems the standard test signals can be applied to give the desired output.
