Abstract
A serial-parallel converter for the reception of telegraphic signals, comprising in particular: a transmission line through which the telegraphic characters are received in serial form; a change recorder that includes as many steps as units has the telegraphic character; a detection circuit that tests the position of the output step of the shift recorder; and a control circuit; these different means being arranged so that before starting the reception of a character, all the steps of the change recorder are in a certain logical position (0, for example) and because in the beginning of the reception of a character, the circuit the control unit tests the input step of the change recorder in a reverse position relative to the initial position (in position 1), the registered bit then representing the character start bit (or flag) and also controls at a point approximately in the center of each significant unit, on the one hand, an advance in a step to the right of the content of the change recorder and, on the other hand, the registration of the condition of the line, in the entry step of the recorder, detecting the detection circuit the arrival of the flag to the exit step, in addition to the successive changes and then signaling the end of the reception of the series character that is then s available in parallel at the outputs of the shift recorder.
