MCQ (Single Correct Answer)

-0.3

The z-Transform of a sequence x[n] is given as X(z) = 2z+4−4/z+3/z². If y[n] is the first difference of x[n], then Y(Z) is given by

$$2z+2-\frac8z+\frac7{z^2}-\frac3{z^3}$$

$$-2z+2-\frac6z+\frac1{z^2}-\frac3{z^3}$$

$$-2z-2+\frac8z-\frac7{z^2}+\frac3{z^3}$$

$$4z-2-\frac8z-\frac1{z^2}+\frac3{z^3}$$
