A soft signal-generator is presented which is created by the exponential functions. Different waveform signals such as ramp function, step function, pulse function and exponential function are available by changing the damping ratio of the compound function created by the exponential functions. 提出一种由指数函数构造的软信号发生器,通过改变由指数函数构造的复合函数的阻尼比,可得到斜坡、阶跃、脉冲和函数等各种不同波形的信号。
A RL circuit is taken into consideration, in which the transient current signal includes a period component varying in sinusoidal waveform and a non-period component varying in exponential waveform. 该算法考虑了RL电路中的暂态电流,假设暂态电流含有一个按正弦规律变化的周期分量和一个按指数规律变化的非周期分量。
We have designed an external defibrillator using the truncated exponential biphasic waveform. The system consists of three parts: the ECG collection module, the control module and the defibrillator module. 研制的双相指数截尾波体外除颤器系统包括心电采集,控制,除颤器三个模块,分别介绍了这三个部分。
