Abstract:
1. An interface apparatus for coupling a signal output to a signal input, comprising: an analog/digital converter unit having an input for receiving an analog signal with a first component and a second component, and having an output for outputting a discrete-value signal associated with the analog signal, the discrete-value signal having a first component and a second component, wherein the analog signal represents a data symbol based on a coding; a signal processor unit connected to the output of the analog/digital converter unit, and configured to output the data symbol represented by the analog signal to an output of the signal processor unit, wherein the signal processor unit comprises a signal processor configured to detect a frequency change or a change in a direction of rotation of the phase angle of the discrete-value signal applied to an input thereof; and a delay unit connected to the output of the signal processor unit, wherein the delay unit comprises a memory unit configured to store at least two data symbols and further configured to provide the data symbol at an output thereof after an adjustable delay time.
