核磁共振测井仪采集信号去噪处理方法
De-noising Method of Nuclear Magnetic Resonance(NMR)Logging Signal
摘要
Abstract
Filters play a very important role in processing NMR data.Most of the time the comb integral filter(CIC)and FIR digital filter are used for multiple processing of NMR data.Taking full advantage of CIC filter,not only can reduce a large number of multiplications,improve system operation speed,but also can reduce consumption of system power.Based on the analysis of design principles of concatenated comb integral filter and FIR digital filter,this paper using the FPGA to design the hardware and selecting the window function of FIR digital filter through Matlab simulation,which are successfully applied to filter the noise of NMR logging tool.关键词
