This document is an experiment report that includes questions about computing inverse z-transforms, determining z-transforms of sequences and their regions of convergence, sketching a pole-zero plot for a causal system, and verifying z-transform expressions using MATLAB. The conclusion discusses learning about the z-transform, which converts discrete time signals into complex frequency representations, and regions of convergence. The experiment involved performing pole-zero plots and verifying z-transforms using MATLAB.

- 6. CONCLUSION : It is concluded that in this lab experiment, i have learned about the Z- Transform that converts a discrete time signal, which is a sequence of real or complex numbers , into a complex frequency domain representation. The Z- transform can be defined as either a one-sided or two-sided transform. The region of convergence (ROC) is the set of points in complex plane for which the Z- transform summation converges. The Z-Transform exists for many signals that do not have a discrete-time Fourier transform. We have Performed Pole-zero plot For different Sequence and Verify Z-Transform Expression Using MATLAB.
