PURPOSE:To perform transmission and receiving of various kinds of signal among plural units which constitute one apparatus, by transmitting and receiving plural signals as PAM multiplex signals and transmitting a reset signal from a one-side unit to establish synchronization. CONSTITUTION:Analogue signals inputted from input terminals IN1 to IN8 become PAM multiplex signals by multiplexer/demultiplexer MP1 and are transmitted to the other transmission/receiving unit through signal cable L1. PAM multiplex signals led to multiplexer/demultiplexer MP2 are separated for every channel and are demodulated and are outputted from output terminals OUT1' to OUT8'. When signals are switched by the number of channels corresponding to one circulation of MP2, a reset signal is outputted from reset timing generation circuit RS to counter CT, and this counter CT is reset at every one circulation switching. |
