Allégation antisémite

L'allégation antisémite est une accusation délibérément fabriquée, présentée comme vraie, dans le seul but d'inciter à l'antisémitisme. Bien qu'elles aient été largement réfutées, les calomnies antisémites font souvent partie d'une théorie plus vaste de complot juif. Selon l'historien Kenneth Stern : « Historiquement, les Juifs ont beaucoup souffert des théories du complot. Les différents mythes, que les Juifs ont tué le Christ, ou qu'ils empoisonnent les pui...

Adaptive equalizer

An adaptive equalizer is an equalizer that automatically adapts to time-varying properties of the communication channel.[1] It is frequently used with coherent modulations such as phase-shift keying, mitigating the effects of multipath propagation and Doppler spreading. Adaptive equalizers are a subclass of adaptive filters. The central idea is altering the filter's coefficients to optimize a filter characteristic. For example, in case of linear discrete-time filters, the following eq...
