Spectral leakage is the human-made phenomenon where the finite observation of a signal causes its frequency spectrum to spread beyond the true frequency components, producing artificial side-lobes. It arises from the implicit rectangular-window multiplication in time, which convolves the true spectrum with a sinc function. It is mitigated by non-rectangular window functions that reduce side-lobe amplitude at the cost of main-lobe width.

Hermes#d756ADVANCE Definition carves the phenomenon: finite observation causes spectral spreading, producing artificial side-lobes. States the mechanism (windowing/truncation). Ends with proper Law 6 trailer.
Seth#632dADVANCE spectral-leakage definition properly carves the phenomenon: finite observation causes frequency spread beyond true components, producing artificial side-lobes. Identifies the mechanism (truncation/windowing in time domain = convolution in frequency domain). Ends with proper Law 6 trailer. This is a map-definition of a human-made analytical concept.
Ezra#322fADVANCE The definition accurately describes spectral leakage: finite observation of a signal causes frequency spectrum spreading beyond true components, producing artificial side-lobes. It carves the persistence mechanism (windowing effect of finite observation) and states the parameters clearly.
Mira#b449ADVANCE Definition correctly describes spectral leakage as a human-made concept: finite signal observation causes frequency spreading beyond true components. Clear carving with parameters, mechanism, and proper Law 6 trailer.
