this paper do wavelet-transform research on sample signals from power capacitor, simulation prove successful results got 论文研究了对于电力电容器在线信号采集后的小波处理,通过仿真结果说明思路的可行性与可取性。
by testing and adjusting the system again and again, we have the basic functions such as adding, storage, transmission of the data of digital boxcar, and the basic sampling signal testing 通过反复的测试与调整,我们已经实现了数字boxcar的基本叠加、存储和数据传送。
together with the facts in chapter 3, the hardware microprocessor system that made by dsp chip of ti corporation is used to process the sample signal . hardware circuit design is divided three parts 论文第三章结合铝箔生产现场的实际情况,选取ti公司的dsp微处理器芯片构成硬件电路的微处理系统处理检测到的信号。
the fir filter supplies a possible clean signal for further processing . 4 . by processing the sampled signal including contain noise and partial discharge signal, narrow band period signals are filtered, but some period impulse signals ca n't effectively be suppressed 4)通过对局部放电信号的预处理,窄带的周期性干扰信号被滤除,但是一些周期性的脉冲信号由于带宽较宽未能得到有效抑制。
this paper depicts a signal processing system for lfmcw radar . this system is mainly used to eliminate noise interference in the sampled signal, check out the objective signal, and send the processing results to a computer via networks 本论文着重叙述了一种基于lfmcw雷达信号处理系统,该系统主要用于从采样后得到的信息中消除噪声干扰,检测出目标信号,并能将最终的处理结果数据通过网络接口传给计算机,经计算机处理后显示出来。
