![**Title:** Calculating Energy and Power of a Signal
**Problem Statement:**
Find the energy and power of the signal shown in the plot. All points not shown are zero.
**Diagram Explanation:**
The plot is a discrete signal representation on a graph with the x-axis labeled as \(n\) and the y-axis representing the amplitude of the signal \(x(n)\). The graph spans from \(n = -2\) to \(n = 4\).
**Signal Values:**
- \(x(-1) = 1\)
- \(x(0) = 3\)
- \(x(1) = 2\)
All other points (not shown in the plot) are considered as zero.
**Objective:**
1. Determine the energy of the signal.
2. Determine the power of the signal.
**Additional Instructions:**
Use the formula for energy and power specific to discrete signals:
- **Energy (E)** of a discrete signal \(x(n)\) is given by: \[ E = \sum_{n=-\infty}^{\infty} |x(n)|^2 \]
- **Power (P)** of a discrete signal \(x(n)\) over a period \(N\) is given by: \[ P = \frac{1}{N} \sum_{n=0}^{N-1} |x(n)|^2 \]
For this exercise, assume \(N\) is the total number of samples in the signal (including zeros) if needed.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4bdca33e-fe41-4c4f-b2f7-f887541be3fa%2F2609b93b-0210-41cf-87af-6eb0151a77ad%2Fkhqg7fp_processed.png&w=3840&q=75)
