Abstract:
1. A system for runtime compensation of a runtime difference produced by emulating a high-frequency signal, comprising: a transfer unit which receives an input signal and produces an output signal x(t); a signal processing unit, which receives the output signal x(t) and emulates the signal x(t) by producing an emulated signal {circumflex over (x)}(t), the signal processing unit causing the runtime difference; a difference unit to determine a difference signal between the signals x(t) and {circumflex over (x)}(t); and a filter through which the emulated signal {circumflex over (x)}(t) is routed, the filter being connected between the signal processing unit and the difference unit to filter the emulated signal {circumflex over (x)}(t) before the emulated signal {circumflex over (x)}(t) is fed to the difference unit the filter having a negative group runtime in a certain frequency range.
