Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - The requirement of causality in system theory is inevitably accompanied by the appearance of certain mathematical operations, namely the Riesz proj- tion,theHilberttransform,andthespectralfactorizationmapping.Aclassical exampleillustratingthisisthedeterminationoftheso-calledWiener lter(the linear, minimum means square error estimation lter for stationary stochastic sequences [88]). If the lter is not required to be causal, the transfer function of the Wiener lter is simply given by H( )= ( )/ ( ),where ( ) xy xx xx and ( ) are certain given functions. However, if one requires that the - xy timation lter is causal, the transfer function of the optimal lter is given by 1 ( ) xy H( )= P , ( , ] . + [ ] ( ) [ ] ( ) xx + xx Here [ ] and [ ] represent the so called spectral factors of ,and xx + xx xx P is the so called Riesz projection. Thus, compared to the non-causal lter, + two additional operations are necessary for the determination of the causal lter, namely the spectral factorization mapping ([ ] ,[ ] ),and xx xx + xx the Riesz projection P . …
