摘要
Abstract
In order to quickly and accurately extract target information in ultrasonic guided wave signal,pipeline addition tree array structure is used to design low-order filter,and direct low-order stack is used to realize 20-order high-precision bandpass filter.The digital algorithm of this structure is optimized by combining Pipeline technology and FPGA on-chip resources,and it is applied in nickel-chromium alloy ultrasonic guided wave temperature measurement system.The results show that the designed filter can take about 1047 clocks to filter a 512-point mixed ultrasonic guided wave signal.The overall design of this filter is simple and can achieve real-time filtering function.关键词
