Tang Cong-ming · Jisuanji fangzhen · 2005
The paper introduces a method of baseband remote transmission for digital singal realized by making digital signal amplified by band-pass filter, enhancing power and driving ability by audio power amplifier, and using low frequency component being filtered by the low-pass filter. It establishes a transmission link model for simulation depending on link data theory and trait of practical applied cable. It validates the correctness of designed circuit by simulaton with Matlab, and provides a practical circuit. The technology is successfully applied in transmitting command signal highroad emergency system.
