| Abstract: | In recent years,a lot of research work has been developed to detect low-level signals.The most conventional detection methods are that the lock -in amplifiers are based on the principle of correlation to detect periodical signals and the superposition technique is based on utilizing the essential difference between noise and the detected signals etc.This paper emphatically mentions that the microcomputers can be applied to realizing of the method of smoothing data of the motive points' multinomials so as to detect the low-level signals submerged in noise. |

| Keywords: | the motive points' multinomials noise the low level signals submerged in noise A/D-D/A converter |
