我们研制了一种应用8031单片机的可编程刺激器,其功放电路输出电压幅度高且可由计算机控制。通过编程,该刺激器可输出波形为单次脉冲、串脉冲和正弦调幅波脉冲的刺激脉冲,其主要性能是幅度:0～250V;频率:0～10Hz;脉宽:0.1～1ms;脉冲的上升时间和下降时间:<10μs。
We developed a programmable stimulator using the 8031 microcontroller, the amplifier circuit output voltage amplitude and can be computer-controlled. Through programming, the stimulator can output the stimulus pulse whose waveform is a single pulse, a series pulse and a sinusoidal amplitude modulation wave pulse whose main performances are amplitude: 0-250V; frequency: 0-10Hz; pulse width: 0.1-1ms; pulsed Rise and fall times: <10μs.
