A facsimile receiver, wherein the carrier, which is necessary to reproduce the carrier in the case where the received signal is demodulated through synchronous detection, is reproduced exactly in the carrier reproducing means in the facsimile receiver before the arrival of the picture signal at the facsimile receiver, by supplying also to the demodulating means the communication control signal to be sent from the facsimile receiver to the transmitting station before the transmission of the picture signal from the transmitting station. Moreover, by operating the PLL circuit in the carrier reproducing means in response to all the carrier components in the picture signal, a very quick compensation can be made for phase jitter generated in the telephone circuit so that an exact carrier can be maintained, and the distortion of the reproduced picture can be minimized. |
