Computer ethics the 1940s with MIT professor Norbert Wiener, the American mathematician and philosopher. While working on anti-aircraft artillery during World War II, Wiener and his fellow engineers developed a system of communication between the part of a cannon that tracked a warplane, the part that performed calculations to estimate a trajectory, and the part responsible for firing. Wiener termed the science of such information feedback systems "cybernetics," and he discussed this new field with its related ethical concerns in his 1948 book, "Cybernetics". In 1950, Wiener's second book, "The Human Use of Human Beings", delved deeper into the ethical issues surrounding
Wiener–Khinchin theorem errors can show up as a divergence when the sequence length is modified. Some authors refer to formula_23 as the autocovariance function. They then proceed to normalise it, by dividing by formula_24, to obtain what they refer to as the autocorrelation function. Wiener–Khinchin theorem In applied mathematics, the Wiener–Khinchin theorem, also known as the Wiener–Khintchine theorem and sometimes as the Wiener–Khinchin–Einstein theorem or the Khinchin–Kolmogorov theorem, states that the autocorrelation function of a wide-sense-stationary random process has a spectral decomposition given by the power spectrum of that process. Norbert Wiener proved this theorem for the case of a deterministic function
