| Abstract: | A logging signal acquisition and processing system based on DSP is developed.The hardware and software design is introduced,and realizing process of signal acquisition and processing with the method of digital signal processing is described with the example of Manchester.DSP realizes real-time acquisition and processing of logging signals by acquisition and processing software,so the system can adapt lots of bore hole instruments with different transmission methods,with excellent expansibility.The results of experiment on several logging signal based on the designed system shows that the processing of corresponding signal with the algorithm presented is good,and the system can effectively achieve the desired function. |
