After learning how to extract features from signals, you are now ready to apply your knowledge to real-world signal data. In practical electrical engineering, it is essential to quickly summarize and interpret measurements using statistical tools. The most common statistics for signal analysis are mean, RMS (root mean square), and peak-to-peak values. The mean gives you the average voltage level, the RMS provides a measure of the signal’s effective power, and the peak-to-peak value shows the total voltage swing. Interpreting these statistics helps you understand the nature of the signal, such as whether it is centered around zero, has significant fluctuations, or contains high energy.
