基于声卡的RLC电路稳态特性(相频部分)采集系统

the Acquisition System for RLC Circuit Steady State Characteristic(phase frequency part)Based on Sound Card

介绍了基于声卡的RLC电路稳态特性(相频部分)采集系统。系统以Delphi作为开发平台,声卡为数据采集卡,调用Windows标准API函数编程而成。主要包括数据实时采集、波形实时显示、数据分析处理、结果显示、采集数据保存和数据回放。实验结果表明系统是成功的。

Introduction the Acquisition System for RLC Circuit Steady State Characteristic(phase frequency part) Based on Sound Card.For this acquisition system,Delphi was a development platform.The sound card was an acquisition card.The program was designed through calling Windows standard API function.The system was composed of six parts:acquiring the data in real-time,displaying the waveform in real-time,analyzing and processing the data,showing the result,saving the collection data and Data playback.Experiment results prove that the system is successful.
