If ztransform 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.
Consider three different signal
fig.shows the three different region. Choose the correct option for the ROC of signal
R_{1} , R_{2} , R_{3}
Given
For three different ROC consider there different solution of signal x[n] :
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 = 34. The time signal x[n] is
x[n] is rightsided, X (z) has a signal pole, and x[0] = 2, x[2] = 1/2. x[n] is
The ztransform function of a stable system is given as
The impuse response h[n] is
The ztransform of a signal x[n] is given by
