10.1 General
While periodic signals can be decomposed into a sum of harmonic signals (Fourier series, § 2.6 ), and transient signals represented as Fourier integrals, there is an important category of signals that cannot be so precisely defined. They are characterized by instability over time and a lack of reproducibility over successive recordings. Examples include ships in...
