Answer the following difficult questions correctly and ensure your working is also correctly and easy to understand!
1.Given signal x(n)= anu(n)+bnu(-n-1), determine the ROC of the z- transform.
2.The entire z- plane, except at z=0 is the ROC of which signal?
3.How can you illustrate the following sequence 1/2[X(z)+X*(z*)]. Give an assumption.
4.Solve and illustrate your finding in the signal x(n)=(n-n0).
5.Solve and illustrate for x(n)=(n-k) the 1- sided z- transform.
6.Given 5+7z-1+z-3 as a one-sided z- transform X+(z), solve for the signal x(n)
7.The LTI of a causal system has function H(z)=1/10.5z1+2/13z1. Determine the ROC of H(z).
8.When does a system become BIBO stable and causal?
9.Determine the equation satisfied where |z| equals 101/2 .
10.Re(z)-Im(z) equals to 1 for complex numbers z where z+z is the root of x2-10x+16=0. Determine the equation with roots Re(z) and Im(z).
