景当今世界在以电子信息技术为前提下推动了社会跨跃式的进步,科学技术的飞速发展日新月异带动了各国生产力的大规模提高。由此可见科技已成为各国竞争的核心,尤其是电子信息技术更显得尤为重要,在国民生产各部门电子信息技术得到了广泛的应用。目前单片机渗透到我们生活的各个领域,几乎很难找到哪个领域没有单片机的踪迹。漫步在繁华的现代化的大都市的大街上,随时都可以看到街上有很多可以用卡取钱的机器ATM自动柜机,十字路口的交通灯。我们的手机,我们家里数码电视机、数码音响、遥控器、空调、智能玩具。导弹的导航装置,飞机上各种仪表的控制,计算机的网络通讯与数据传输,工业自动化过程的实时控制和数据处理,广泛使用的各种智能IC卡,民用豪华轿车的安全保障系统,录像机、摄像机、全自动洗衣机的控制,以及程控玩具、电子宠物等等,这些都离不开单片机。更不用说自动控制领域的机器人、智能仪表、医疗器械了,给我们生活带来了处处方便。。这些“高科技”看上去是如此的神秘,它到底是怎样构成的,它是通过什么样的程序和什么样的方式来完成这一系列指令的呢让我们取钱更方便、避免城市的交通混乱和交通阻塞。其实这也是用单片机来控制的,单片机在我们生活中触手可及,它是如此地贴近我们的生活,单片机给我们的生活带来的有如此多的便利。单片机的学习、开发与应用将造就一批计算机应用与智能化控制的科学家、工程师。科技越发达,智能化的东西就越多,使用的单片机就越多。看来学单片机是社会发展的需求。据统计,我国的单片机年容量已达1-3亿片,且每年以大约16的速度增长,但相对于世界市场我国的占有率还不到1。特别是沿海地区的玩具厂等生产产品多数用到单片,并不断地辐射向内地,这说明单片机应用在我国才刚刚起步,有着广阔的前景。培养单片机应用人才,特别是在工程技术人员中普及单片机知识有着重要的现实意义。函数发生器是一种能够产生多种波形,如三角波、锯齿波、矩形波(含方波)、正弦波的电路。函数发生器在电路实验和设备检测中具有十分广泛的用途。通过对函数波形发生器的原理以及构成分析,可设计一个能变换出三角波、正弦波、方波的函数波形发生器。在现代电子仪器中,信号发生器是一类十分重要的仪器,随着电子测量技术与计算机技术的紧密结合,各种波形发生器应运而生它可以产生由用户定义的任意复杂的波形,因而具有广阔的应用发展前景在调试硬件时,常常需要加入一些信号,以观察电路工作是否正常。虚拟仪器是在近20年来兴起的新技术,它逐步改革了测量和自动化的方法,从而达到缩短产品的开发时间,提高产品品质并且降低生产成本的目的,而且与硬件设备的紧密集成使它更简单
