双指数脉冲的产生与分析

文中推导了双指数脉冲函数的参数ｙｍ＝Ｔｍ／Ｔｍａｘ与ｘ＝ｂ／ａ之间的近似关系式，其中，Ｔｍａｘ和Ｔｍ分别为脉冲峰值时间及脉冲后沿半峰值时间。详细分析了采用单位冲击函数和阶跃函数产生双指数脉冲的双口网络，给出了参数设计的原则。

On the Analysis and Generation of the Double Exponential Function

In this paper an approximate relation between the ratio ym = Tm/Tmaxis derived, where Tmax and Tm are, respectively, the times to reach the peak value Fmax and the value fmax/2 on the tail of the pulse, and the ratio x = b/a. We also present a detailed study of the problem of synthesizing an RC two-port, for generating double exponential function f (t) from an impulse function, as well as from the step function. The design principle of RC two- port parameter is given.
