Abstract
The development of a multi-channel interior communication system utilizing a single wire as a transmission line was undertaken in this paper. The principle of time multiplexing was used incorporating the Pulse Amplitude scheme of modulation. Synchronization was accomplished by continuously transmitting a synchronization pulse from one "Master" station to all other "Slave" stations. This system permits mutually exclusive conversations between any stations concurrently. A master station and one slave station were built and tested. Using a 10-kHz sampling frequency, a frequency response of from 100 Hz to 4.8 kHz was obtained. By using solid-state devices throughout, the size and weight of each station are minimized. This in conjunction with the need for only one connecting wire, make this system ideal for modern aircraft.
