WebbNyquist-Shannons samplingsteorem, även kallad Nyquistteoremet, Shannonteoremet eller samplingsteoremet, talar om med vilken frekvens man måste mäta en vågrörelse med hjälp av sampling för att kunna återskapa signalen. Teoremet går i grova drag ut på att man måste, för att undvika fel, sampla med en frekvens som är minst dubbla signalens … Webb23 apr. 2008 · This is called Shannon’s noisy channel coding theorem and it can be summarized as follows: A given communication system has a maximum rate of …

WebbShannon entropy is the creation of Shannon (1948) based on the experiences in Bell System Company during and after the Second World War. Then, Renyi (1961) generalized it for one parameter families of entropies. This entropy for discrete random variables is non-negative but it can be negative in continuous case.
