双脉冲发生器的功能是:当输入信号?为矩形波时,对应于其上升沿及下降沿,产生方向相同的脉冲输出信号?即:对应于每一个矩形波输入信号,将得到两个同方向的脉冲输出信号.图1是一种最简单的双脉冲发生器的线路,它是一个具有射极偏置电阻的放大器.适当地选择R_?、R_?和R_0的数值,就可以使晶体管BG在从放大状态过渡到饱和状态,以及从饱和状态返回到放大状态的过程中,得到幅度较大的同方向脉冲信号.下面,就它的工作原理及参数的选择进行简要的
The function of the double pulse generator is: when the input signal is a rectangular wave, corresponding to its rising edge and falling edge, produce the pulse output signal with the same direction, namely: Corresponding to each rectangular wave input signal, Direction of the pulse output signal Figure 1 is the most simple two-pulse generator circuit, it is an emitter bias resistor amplifier appropriately selected R _ ?, R_? And R_0 value, you can make the transistor BG in the state of transition from the amplifier to the saturation state, and from the saturation state to return to the state of amplification, the amplitude of the same direction to get the pulse signal. Below, its principle of operation and the choice of parameters for a brief
