PCT No. PCT/SE96/00664 Sec. 371 Date Jan. 8, 1997 Sec. 102(e) Date Jan. 8, 1997 PCT Filed May 22, 1996 PCT Pub. No. WO96/37987 PCT Pub. Date Nov. 28, 1996A device and a method correct deviation when transferring an information-carrying signal between a transmitter and a receiver. The transmitter can transmit with a plurality of frequencies generated by a voltage-controlled oscillator used for phase demodulation. The receiver demodulates the modulated information-carrying signal. A detector measures the deviation of the modulated information-carrying signal via the information-carrying signal demodulated in the receiver. The frequencies of the demodulated information-carrying signal can be adjusted so that the correct deviation is obtained, and a correct phase demodulation can be carried out.
