| Abstract: | According to the case that control systems are required high reliability and real time reaction in underground production environment, the dual tone multi-frequency technique is applied to long distance transmission of low-rate signals in the strong noise environment. This paper analyzes and proves the anti-noise capability of dual tone multi-frequency way of transmitting signals by dual ton signals, takes the example of special MT8888 chip to design and realize the e multi-frequency technique. |
