The output response of a first order system with excitation is: (a) (y=xleft(1-e^{-t / tau} ight)) (b)

The output response of a first order system with excitation is:

(a) \(y=x\left(1-e^{-t / \tau}\right)\)

(b) \(y=x e^{-t / \tau}\)

(c) \(y=x\left(1+e^{-t / \tau}\right)\)

(d) \(y=x\left(1-e^{t \tau}\right)\)
