Question

The transfer function of a system having the input as X(s) and output as Y(s) is?

(a) Y(s)/X(s)

(b) Y(s) * X(s)

(c) Y(s) + X(s)

(d) Y(s) – X(s)

This question was posed to me in an online quiz.

This is a very interesting question from Transfer Function in section Application of the Laplace Transform in Circuit Analysis of Network Theory

Answer 1

Correct answer is (a) Y(s)/X(s)

The best explanation: The transfer function is defined as the s-domain ratio of the laplace transfrom of the output to the laplace transfrom of the input. The transfer function of a system having the input as X(s) and output as Y(s) is H(s) = Y(s)/X(s).
