Digital Electronic MCQ Set 1 1. Which of the following justifies the linearity property of z-transform?[x(n)↔X(z)]. a) x(n)+y(n) ↔X(z)Y(z) b) x(n)+y(n) ↔X(z)+Y(z) c) x(n)y(n) ↔X(z)+Y(z) d) x(n)y(n) ↔X(z)Y(z) AnswerAnswer: b [Reason:] According to the linearity property of z-transform, if X(z) and Y(z) are the z-transforms of x(n) and y(n) respectively then, the z-transform of x(n)+y(n)…
