取样积分器的参数选择

The choice of Parameters to Sampling Integrator

合理地选定取样积分器参数可以保证最佳的信号测试结果,但就具体的几个主要参数,如,取样脉冲宽度、时基锯齿波宽度、积分器时间常数、慢扫描时间等,其间关系错综复杂,并受积分器类型的影响,具体按照何种选定原则并不绝对,还要根据具体实验需要及取样积分器类型进行综合考虑权衡。

Reasonable parameters of the selected sampling points can guarantee optimal signal test results,but several major specific parameters,such as Tg - the sampling pulse width,TB - the width at the base sawtooth,TC -integrator time constant,TS -slow scan time,between which the relationships are complex,influenced by the kinds of integrators.It is not certain how to select the specific principles but also dependent upon the specific experimental needs and the types of sampling integrators.
