Abstract
For a demodulator for radio data signals, where transmission of these signals is carried out through phase shifting of a suppressed subcarrier, where a multiplex signal, which contains a signal with the frequency of the subcarrier passes through a band-pass filter and an amplitude limiter, the amplitude-limited signal having a subcarrier frequency is transformed into digital sampling values, if necessary by additional filtering, and the sampling values are supplied to at least one phase control loop for deriving a bit clock signal.
