摘要
给出了由数字仪的指数波响应求冲击响应的计算公式,推导了考虑发生器回路电感后由两种指数波响应求冲击响应的计算公式,从而系统地解决了数字仪冲击测量误差理论计算的难题。对于计算公式的准确度又作了讨论,指出了采样初相位的计算误差对冲击测量误差的计算基本没有影响。这些计算公式为数字仪冲击测量误差开拓了理论计算的新途径。
The calculation formulas of impulse response from exponential wave response of the digitizer are given, and calculation formulas from two kinds of exponential responses in consideration of inductance in the generator circuit are deduced. Thus, the difficult problem concerning theoretical calculation of impulse measurement errors of digitizers is systematic solved. Calculation accuracy is also discussed. It is pointed that calculation error of the initial phase of sampling points has basically no influence on calculation of impulse measurement errors. These caJculation formulas develop a new way for theoretical calculation of impulse measurement errors of digitizers.
