The principle that continuous-time bandlimited signals can be completely represented and reconstructed from discrete amplitude samples taken at or above the Nyquist rate is a foundational theorem in signal processing and everyday observation requiring no citation.
The claim is a fundamental, textbook definition of the Nyquist-Shannon sampling theorem, making it common knowledge in electrical engineering and signal processing. None of the provided papers directly discuss or challenge this foundational theorem in a way that requires empirical arbitration.
