ANALOG SIGNAL MULTIPLEX TRANSMISSION DEVICE AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To provide an analog signal multiplex transmission device that deterioration of a signal in a transmission line is less, of which constitution is simple and which can be miniaturized with respect to an analog signal multiplex transmission device transmitting/multiplexing plural input analog signals. SOLUTION: Plural transmission devices 1a-1n provided with analog/digital conversion means 11a-11n converting input analog signals into digital signals and outputting them to transmission lines 2a-2n, and a reception device 3 provided with a digital addition means adding the digital signals from plural transmission devices and outputting digital addition signals and with a digital/analog conversion means 32 converting the digital addition signals into the analog signals and outputting analog multiplex signals are provided for the titled device. Plural transmission devices and reception devices are connected in a star form through plural transmission lines.
