Digital polyphase filter bank with maximum sampling-rate reduction

摘要

the cost of transmission and storage of signals, it is necessary to reduce the maximum taktreduktion paradigm to pursue. for the special case of a zweikanaligen paradigm is a quadrature mirror filtering, solution known in any spectral ru00fcckfaltungsanteile in synthesis paradigm, are compensated.through the above zweikanaligen interconnection filterbu00e4nke according to a tree structure, a hu00f6herkanalige paradigm with maximum taktreduktion can be realized. in the event that a maximum taktreduktion in the paradigm is necessary, can also be the combination of a digital polyphasen network with a processor for discrete fourier transformation are used.;even with the use of the above combination to a maximum to be able to make taktreduktion in splitting the input signal using the digital polyphasen network emerging m complex teilbandsignale further taktreduktion by offset unterabtasten de r real and imaginu00e4rteilsignale tests.this can occur at the maximum taktreduktion ru00fcckfaltungsverzerrungen in synthesis paradigm offset.
