Question

An inverse system with the original system gives an output equal to the input. How is the inverse system connected to the original system?

(a) Series

(b) Cascaded

(c) parallel

(d) No connection

The question was posed to me during an interview.

I need to ask this question from Properties of Systems topic in section Signals and Systems Basics of Signals and Systems

Answer 1

Correct answer is (c) parallel

To explain I would say: An inverse system when cascaded with the original system gives an output equal to the input.
