A facsimile circuit for a transmitter or a receiver, having an automatic switch-over between a photo and a text information signal processing. The more or less analog changing, photo information signal and the pulse-shaped changing, text information signal are converted into a binary signal suitable for supply to a reproduction device. A detection circuit, which performs a dual signal differentiation for detecting the presence of photo or text information controls a switch-over device through which the facsimile signal becomes available for transmission and/or reproduction after it has passed through an analog-binary or pulse-binary signal conversion circuit respectively. |
