QUESTION: 1

Solution:

QUESTION: 2

X (z) = ln (1 + z^{-1} ), |z|>0

Solution:

QUESTION: 3

If z-transform is given by

X (z) = cos ( z ^{-3}), |z|> 0,

The value of x[12] is

Solution:

QUESTION: 4

X (z) of a system is specified by a pole zero pattern in fig. P.5.4.36.

Consider three different solution of x[n]

Correct solution is

Solution:

All gives the same z transform with different ROC. So all are the solution.

QUESTION: 5

Consider three different signal

Fig. P.5.4.37 shows the three different region. Choose the correct option for the ROC of signal

Solution:

x_{1[}n] is right-sided signal

QUESTION: 6

Given

For three different ROC consider there different solution of signal x[n] :

Correct solutions are

Solution:

So (b) is wrong.

QUESTION: 7

X (z) has poles at z = 1/2 and z = -1. If x [1] = 1 x [ -1] = 1, and the ROC includes the point z = 3/4. The time signal x[n] is

Solution:

Since the ROC includes the Z = 3/4, ROC is

QUESTION: 8

x[n] is right-sided, X (z) has a signal pole, and x[0] = 2, x[2] = 1/2. x[n] is

Solution:

x[n]= Cp^{n}u[n],x[0=2=C

QUESTION: 9

The z-transform function of a stable system is given as

The impuse response h[n] is

Solution:

h[n] is stable, so ROC includes |z|= 1

QUESTION: 10

Let The unilateral z-transform is

Solution:
