METHOD AND DEVICE FOR DEMODULATING

METHOD AND DEVICE FOR DEMODULATING

The invention relates to a method and device for demodulating a received input signal (E1) containing a modulated up data signal (D). The input signal (E1) is mixed with a comparison signal (V) to form an intermediate frequency signal (ZF1) from which a conditioned intermediate frequency signal (ZF2...

description The invention relates to a method and device for demodulating a received input signal (E1) containing a modulated up data signal (D). The input signal (E1) is mixed with a comparison signal (V) to form an intermediate frequency signal (ZF1) from which a conditioned intermediate frequency signal (ZF2) is generated. In a control unit (6), the data signal (D) is recovered from the conditioned intermediate frequency signal (ZF2), particularly by sampling the data signal (D). The comparison signal (V) used for mixing and, in particular, also a sampled signal (A1) used for scanning, as well as a transmitted signal (S1, S2) that underlies the input signal (E1) are derived from the clock signal (T) provided for the clock supply of the control unit (6). As a result, only a single clock generator (16) is required.
