At first, hardware circuit of the system has been designed, including minimum system of DSP, sampling pretreatment, dead zone formation, constantamplitude control and display circuit.
To design and manufacture a constant-source with adjustable amplitude value and the test system, and to realize the examination of zener diode voltage drift parameter, is very important.
设计制作出一个幅值可调的恒流源及其测试系统，实现稳压二极管电压漂移参数的检测，至关重要。
