6、技术理论学习，促进其工程应用，着重于提高学生的电子技术实践技能，培养学生综合运用所学知识分析问题和解决问题的能力，了解开展科学实践的程序和基本方法，并逐步形成严肃、认真、一丝不苟、实事求是的科学作风和一定的生产观、经济观和全局观。1.2课程设计的任务设计方波——三角波——正弦波函数信号发生器。1.3课程设计的技术指标.设计.组装.调试函数发生器2.输出波形正弦波.方波.三角波3.频率范围0.02—20kHZ范围内可调4.输出电压方波幅值为5V正弦波幅值为±5V三角波峰-峰值为5V占空比可调。1.4课程设计题目及要求信号发生器是一种能够产生多种波形,如三角波

7、、锯齿波、矩形波（含方波）、正弦波的电路被称为函数信号发生器。函数信号发生器在电路实验和设备检测中具有十分广泛的用途，可以用于生产测试、仪器维修和实验室，还广泛使用在其它科技领域，如医学、教育、化学、通讯、地球物理学、工业控制、军事和宇航等。它是一种不可缺少的通用信号源。产生正弦波、方波、三角波的方案有多种，如：①首先产生正弦波，然后通过整形电路将正弦波变换成方波，再由积分电路将方波变成三角波；②也可以首先产生三角波—方波，再将三角波变成正弦波或将方波变成正弦波；③也可以通过单片集成函数发生器8038来实现……。先是对电路的分析，参数的确定选择出一种最适合
