摘要:
A simple inexpensive analog transmission system is realized using a dual-channel-color LED assembly, a plastic optical fiber, a dual-channel-color sensor assembly, and a crosstalk elimination circuit. The transmission system, covering dc to 10 kHz, has a distortion factor of less than 2% and a crosstalk of less than -40 dB, and is suitable for use in factory communications.
