Abstract

An apparatus for diagnosis of a communication channel, wherein a communication signal serves for data transmission and is a frequency-modulated signal. The apparatus includes a receiving circuit, which serves for receiving the frequency-modulated signal. The receiving circuit includes a monitoring unit, which serves for determining a signal parameter of the frequency-modulated signal. The receiving circuit also includes a demodulator, which serves to demodulate the frequency-modulated signal. The receiving circuit also includes a signal processing unit, which is connected with the demodulator and with the monitoring unit, wherein the signal processing unit, at least at times, serves for evaluating the signal parameter of the frequency-modulated signal determined by means the monitoring unit and, at least at times, for evaluating the demodulated signal.
