Besonderheiten in der Theorie der linearen Übertragung zeitdiskreter Signale mit Taktumsetzung bei rationalem Taktverhältnis (Teil I)

This paper deals with linear, time invariant systems for the processing of time-discrete but continuous valued signals with a different sampling rate at the input and output terminal. It is shown that the analytical description of the signal processing can be simplified (compared to the methods used in the literature), for a rational factor of the sampling rate conversion. Illustrative equivalent circuits of the over-all system can be derived. The connection to the theory of signal processing with an irrational factor of sampling rate conversion is established.
