1、毕业设计（论文）中文摘要随着电子技术的不断发展，电子仪器的发展也是令人瞩目的。总的来说，电子仪器有两个方向的发展趋势：一是向多功能、多参数、高精度、高速度方面发展，另一个是向实用化、小型化、数字化、廉价的通用或单一用途方面发展。对于数字式电压表来说，一方面趋向于合并于数字式万用表中，另一方面趋向于使用方便、小型廉价的单一用途电压表。本次的毕业设计课题为数字交流毫伏表，其显著特点是测量范围宽，可以实现量程自动转换，操作简单，使用方便。该电压表还具有在—定的测量范围内将量程自动选择在最佳位置的功能，从而可以快速、方便、
2、准确地测量电压，在设计中我采用了模块化的设计方法，先将整机分为不同的功能模块，再设计实现局部功能的单元电路。这样各单元电路的功能明确，之间的界限清楚，便于调试。本文对输入通道的设计、反相放大器的设计、AC／DC转换部分的设计、量程自动转换电路的设计作了详细的介绍。关键词：数字交流毫伏表测量转换30毕业设计（论文）外文摘要Title:DigitalAcmVthedesigntableThedesignofdigitalACmVmeterAbstract:Withthecontinueddevelopmentofele
