GATE EE 2005

MCQ (Single Correct Answer)

-0.6

If u(k) is the unit step and $$\delta\left(k\right)$$ is the unit impulse function, the inverse z-transform of $$F\left(z\right)=\frac1{z+1}$$ for k>0 is:

$$\left(-1\right)^k\delta\left(k\right)$$

$$\delta\left(k\right)-\left(-1\right)^k$$

$$\left(-1\right)^ku\left(k\right)$$

$$u\left(k\right)-\left(-1\right)^k$$
