Signal Magnitude Area (SMA) is a measure used in signal processing, especially in the context of analyzing the characteristics of certain types of signals, such as those in biomedical applications, including electrocardiograms (ECGs). The SMA provides an indication of the magnitude of a signal over a specific period, accounting for both the area above and below the baseline of the signal waveform.
