Question

Find Z-transforms and corresponding regions of convergence for the following signals:

The image contains a list of mathematical expressions used in signal processing. Here is the transcription: c) \( x(n) = - (4)^n u(-n - 1) \) d) \( y(n) = e^{j\omega_0 n} u(n) \) e) \( y(n) = b^n \cos(\omega_0 n) u(n) \) (Hint: use the Euler representation and/or properties of Z-transform) There are no graphs or diagrams in the image. The expressions involve unit step functions and exponential functions, often used in the analysis of discrete-time signals and systems.
