3、绘出原理图在PCB板上进行布线印制出电路板，并将元器件焊接到电路板做出实物板，对实物板进行调试，最后分析出现误差的原因以及影响因素。通过老师的指导和我们不断的学习和研究完成了预想的功能。关键词：函数信号发生器；三种波形；占空比；Multisim；ProtelDXP；调试。22目录摘要引言部分1课程设计的目标与设计任务········································1.1设计的目标····················································1.2设计的要求······························
