Abstract
A carrier control loop (1) for a receiver of digitally transmitted signals is disclosed comprising, in the direction of signal flow, a quadrature demodulator (3), a symbol recognition device (4), a detector (9) for forming a phase deviation value (.phi.d) and/or a frequency deviation value (fd), a feedback device (10), and a variable-frequency oscillator (11) connected to the quadrature demodulator (3). An evaluating device (12) determines from signals (I, Q) of the carrier control loop (1) a reliability value (z) for the measured phase deviation value (.phi.d) and/or frequency deviation value (fd), and controls the carrier control loop (1) in accordance with the determined reliability value.
