Abstract
Supervisory circuit for telegraph signal emitters, characterized by comprising as many matching circuits (A) as significant elements of the adopted code (each of which has its inputs connected to the wires on which, according to the adopted code, it is present, for each of the significant elements of the telegraphic signal, the battery polarity), as many matching circuits (B) (each of which has its inputs connected to the wires on which, according to the adopted code, it is present for each of the significant elements of the telegraphic signal (ground polarity), a first AND circuit (F) that collects the outputs of the circuits (A) and whose output is connected to an input of a first OR circuit (D) to whose other inputs the outputs of the circuits (B) are connected, a second AND circuit (E) that collects the outputs of the circuits (B) and, whose output is connected to an input of a second do OR circuit (0) to whose other inputs the outputs of circuits (A) are connected, and an output circuit (CU) to whose inputs the outputs of circuits (0 and D) are connected.
