Question

What is the rule c*(x*h) = (x*h)*c called?

(a) Commutativity rule

(b) Associativity rule

(c) Distributive rule

(d) Associativity and Commutativity rule

This question was addressed to me in an online interview.

The origin of the question is Properties of LTI Systems in division Time-Domain Analysis of CT Systems of Signals and Systems

Answer 1

The correct answer is (d) Associativity and Commutativity rule

Best explanation: By definition, the commutative rule i h*x=x*h and associativity rule = h*(x*c) = (h*x)*c.
