Method and apparatus for upbeats a discrete-time signals

摘要

A process for the interpolation of input values (x) of an input signal, in which process output values (y) of an output signal can be produced, whereby the sampling sequence frequency of the output signal greater than the sampling sequence frequency of the input signal and the waveform of the output signal essentially of the curve shape of the input signal corresponds to, characterized in that the difference between a first and a subsequent second input value (x) is determined, as a function of the determined difference interpolation values (p0.. pn) of an interpolation process barrel (p, p) and successive scaled output values (y) in each case by addition of the first input value (x) with a scaled interpolation value (p0.. pn) are generated.
