Abstract
The system according to the present invention carries out two way communication of a digital signal between a master terminal having its own clock source and a slave terminal, which is synchronized with the clock of the master terminal. The master terminal sends a digital signal originating from its own clock to the slave terminal and the slave terminal in turn sends a digital signal based on a clock signal which is derived from the received digital pulse from the master terminal.
