Abstract
Based on the practical need of equip-teaching and scientific research, a simple but practical integrated signal transmission system is designed. The system needs only six transmission lines to carry audio, video and control signals. The audio transmission module is most difficult one in the system design, using new integrate amplifier to reduce distortion, using the technolegy of eliminate side tone to aviod self-excitation, which uses tone transformer to realize remote transmission, the video transmission module adopts a new video transceiver, and the control signal transmission module uses RS-485 bus to realize internal system communication. The system communicates with the control computer through serial ports. Actual application proved the feasibility and practicability of this system.
