摘要: A demodulator (100) for demodulating a frequency modulated RF signal (x(t)), includes an input path (101) delivering signal, local oscillator (111), connected to the first mixer (107) mixing output reference from with produce in-phase component of received phase shifter (113), second (109) via quadrature signal; and processor (119) producing demodulated information by function components; wherein is periodically operable in error determination mode signals produced have which offset carrier signal. Also described receiver, method terminal using demodulator.
