【摘要】 本文介绍实现仪表传输函数最佳修正的数字方法。在分析了脉冲波形通过仪表发生畸变的原因后,根据最小均方误差准则导出了最佳数字校正器的设计方法。由于这种校正器的插入,仪表输出脉冲波形的过渡过程得到缩短,仪表导致的畸变也得到一定的修正,从而使仪表或设备的分辨力获得较大的提高。除计算机模拟之外,本文还给出一个实验。计算机模拟和实验都很好地符合了理论上的结论。更多还原

【Abstract】 The digital method of realizing the optimal correction of instrument transmission function is studied in this paper. The reason why pulses are distorted after they go through instruments is analyzed. and the design method of optimal digital correcter is derived according to the least square error principle. With insertion of the correcter, the transient process of output pulse waveform is shortened, and the waveform distortion resulting from instrument is corrected, and the resolution of instrument or apparatus become high. In addition. this paper gives a computer simulation and an experiment which satisfactorily comfirm the conclusion in theory.更多还原
