Question
**Mathematical Expression:** The function \( x_2[n] \) is defined piecewise as follows: - For \( n \geq 0 \), \( x_2[n] = \left( \frac{1}{3} \right)^n \) - For \( n < 0 \), \( x_2[n] = 2^n \) **Explanation:** This piecewise function specifies different formulas depending on the value of \( n \). For non-negative integers (\( n \geq 0 \)), the function decreases exponentially with a base of \(\frac{1}{3}\). For negative integers (\( n < 0 \)), the function follows an exponential growth with base 2.

**Determine the z-transform, including the region of convergence (ROC), of the following signals:** On this page, we explore the concept of the z-transform, a powerful tool in signal processing used to analyze discrete-time signals. One crucial aspect of understanding the z-transform is identifying the region of convergence (ROC) for a given signal. **Figure Analysis:** This educational document provides a starting point for determining the z-transform of various signals. The z-transform enables us to work with sequences and offers insights into system stability and frequency response. Recognizing the ROC helps in understanding where the transform converges, which is essential for practical applications. Whether you're just starting with z-transforms or reviewing fundamental concepts, understanding how to compute the z-transform and analyze the ROC is key to mastering discrete signal processing.
