Amplitude-analysis is the extraction and quantification of a signal's amplitude characteristics. It operates by computing envelope curves via rectification and low-pass filtering, measuring peak amplitudes, and deriving root-mean-square (RMS) energy values. The persistence mechanism is a set of deterministic mathematical operations implemented in digital signal processors and software libraries. It carves the boundary between raw signal amplitude and derived amplitude metrics, enabling signal characterization across audio, communications, and instrumentation domains.

Amplitude-analysis is a measurement technique for signal amplitudes. The concept of measurement predates and fed into amplitude-analysis as a specialized method. Which-came-first test passes: measurement is older and more general.

amplitude-analysis IS a specific kind of signal processing: it applies mathematical techniques to extract and quantify amplitude characteristics of signals (envelope detection, peak measurement, RMS). A competent speaker would call it 'a kind of signal processing.' This is the nearest kind — no 'signal-analysis' entry exists, and amplitude analysis is distinct from spectral-analysis (time-domain vs frequency-domain).
