Construct the inverse system of y(t) = 2x(t)

Electronics and Communication Engineering (ECE) : Signals and Systems - Quiz(MCQ)

y(2t) = x(t)

y(t) = x(2t)

y(t) = 0.5x(t)

y(t) = 2x(t)

Correct Answer : Option (C) : y(t) = 0.5x(t)

Explanation : Now, y(t) = 2x(t) => x(t) = 0.5*y(t)
Thus, reversing x(t) <-> y(t), we obtain the inverse system: y(t) = 0.5x(t)
