1. What Is The Average Power Formula?

The average power formula calculates the average power of a signal over a specified time period. It is defined as the integral of the squared magnitude of the signal divided by the time period.

2. How Does The Calculator Work?

The calculator uses the average power formula:

Where:

• \( P_{avg} \) — Average power
• \( T \) — Time period
• \( s(t) \) — Signal function
• \( |s(t)|^2 \) — Squared magnitude of the signal

Explanation: The formula integrates the squared magnitude of the signal over the period T and divides by T to find the average.

3. Importance Of Average Power Calculation

Details: Calculating average power is essential in signal processing and communications systems for determining signal strength, energy efficiency, and system performance.

4. Using The Calculator

Tips: Enter the signal function in mathematical notation and specify the time period. The function should be properly formatted for accurate calculation.
