Root mean square, a statistic that measures signal energy or amplitude. In audio processing it is often used for background energy detection to determine whether a signal is in a silent or low signal-to-noise state.

Handcrafted time-domain features typically include mean absolute value (MAV), waveform length (WL), zero crossings (ZC), slope sign changes (SSC), and root mean square (RMS), computed on fixed-length sliding windows to compress high-dimensional raw sEMG sequences into low-dimensional descriptors.
