Abstract
Data transmitted from a local terminal to a remote terminal is converted into such a diphase data signal that a data bit of binary '0' is represented by a signal with two transitions, and a data bit of binary '1' is represented by a signal with one transition. Data transmitted from the remote terminal to the local terminal is modulated by the diphase data signal of the local terminal, and delivered to the local terminal in the form of a diphase data signal. In the local terminal, the coded diphase data signal from the remote terminal is demodulated by the diphase data signal of the local terminal, and regenerated into the transmission data of the remote terminal.
