Vc++编写的32位串行通信程序 Vc++编写的32位串行通信程序

利用NI的动态链接库编写的GPIB通信实例，能够初始化8920A测试仪器，能够发送相关的控制命令来控制仪器的工作状态，还能够读取仪器的测试数据，采用标准的gpib32动态链接库，程序通过耐久性测试，在断电之后再通电仍然能够不用关闭软件而直接连接通信。之前是vc的例子调用，在此改为了利用delphi调用相关函数，发送相关控制命令一样实现了delphi的gpib通信程序。

程控滤波器论文。实现了步进为10dB的0到60dB的可调增益。滤波器部分以可编程开关电容滤波器MAX262芯片为核心，实现了截止频率1KHZ-20KHZ步进1HZ可调的程控滤波器，各项误差低于5％。-Program-controlled filter papers. To realize a step from 0 to 60dB in 10dB of adjustable gain. Filter part of programmable switched capacitor filter MAX262 chip as the core, realize the cut-off frequency 1Hz step 1KHZ-20KHZ program adjustable filter, the error of less than 5.
