Abstract
A system for controlling teletype signals, in which a start-stop telegraph signal train may be received at the reversed polarity state. The polarity of a signal element of a received character is decided at a specified instant in a time slot at which the stop element of the received character is expected to arrive. The polarity of a signal element of the received character is again decided in a time slot at which a stop element after a predetermined number of characters from the specified instant is expected to arrive. Only when the polarities of the signal elements of the received characters are decided as the same A-polarity during both of the decision operations, the polarity of the telegraph signal train is automatically reversed.
