If z-transform is given by
X (z) = cos ( z -3), |z|> 0,
The value of x[12] is
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
Consider three different signal
Fig. P.5.4.37 shows the three different region. Choose the correct option for the ROC of signal
Given
For three different ROC consider there different solution of signal x[n] :
Correct solutions are
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
x[n] is right-sided, X (z) has a signal pole, and x[0] = 2, x[2] = 1/2. x[n] is
