【摘要】 本文介绍了一种利用PC机设备来设计模拟信号发生器的方案。该方案通过利用PC机内的充分资源来产生各种所需波形,然后通过USB2.0接口输出。在PC机外采用DAC8580对数字信号进行DA转换,并用CPLD对整个电路进行控制。更多还原

【Abstract】 The design of An Analog Signal Generator based on PC is introduced. This method uses the sufficient resources on PC to generate the digital signal needed and export it through USB2.0 interface. Otherwise, we choose DAC8580 to do DAC, and use CPLD to control the whole circuit outside PC.更多还原
