ABSTRACT:
The transmission system of this invention provides for transmitting over a fiber-optic line serially sampled analog data from a plurality of channels. Each sampled analog signal has a interleaved digital pulse. A sequence of digital pulses provides synchronization data for the determination in the receiver of the output channel for each received sampled analog signal. The digital pulse associated with each sampled analog signal provides the timing for a sampling circuit to provide as an analog signal each of the sampled analog data as an analog signal to a separate channel. The digital pulses not needed for synchronization are used for digital data transmission.
