Can Someone please hep me solve this is problem Please. It is really important and it has 2 parts. both need to be solved. Thank you in advance
A) A DT signal x[n] has the following z-transform X(z)= z+1/2z^2+10z+4
Determine the inverse z-transform, i.e. x[n] for all n Sketch the poles and zeros of X(z), including the unit circle.
Determine whether the system is stable or unstable, why?
B)Determine the z-transform of x[n-2], using the properties table, write it as a ratio of polynomials. Does this signal grow out of bounds?

Compute the poles and zeros of each of the filters given in problem 4. Which filters are stable? 4a) H(z) = 1/1 + z-3 4b) H(z) = (1+3z-1+2z-2)/(1-z-1) *I understand that a system is stable if all poles are strictly inside the unit circle, and unstable if any are outside the unit circle. If a pole is ON the unit circle or the boundary of the unit circle like 1 or -1, would that make it stable or unstable? *I...

5. The z transform is a very useful tool for studying difference equations. Often difference and differential equations are used to describe causal systems and only the causal solution is of interest. This is the "initial condition" problem of a differential equations course. But both difference and differential equations describe more than just the causal system. For instance, "backwards" solutions and "two point boundary value" solutions. One way in which to think about the problem is the ROC of the...
