| Abstract: | The paper presents A/D conversion method and its effect of deep seismic sounding imitation tape data of DSS, which is realized in CROMEMCO microcomputer. In the research process to realize A/D conversion, some tests, such as the method of collecting timescale signal treating time signal with 6 sounds, improving imitating feadback circuit, weredone, which can increase accuracy and effect of the A/D conversion. It is proved by analysing the practice data in Haicheng seismic region that accuracy of the A/D conversion of this system has meet achieved requirements of the standard. |
