摘　　要：周期信号波形识别及参数测量广泛应用于现代电子技术领域中。通过对周期性信号波形进行研究与分析,设计了一种周期信号波形识别及参数测量装置。首先,采用程控放大器对不同幅度的输入信号进行精确放大。然后,基于LF398芯片设计检波电路。在此基础上,通过高速比较器将波形信号转换成TTL信号。最后,利用傅里叶算法对ADC采集后的数据进行处理,从而精确判断波形种类并在LCD上显示。测试结果显示,设计的装置测量精度高、实时好,能为周期信号识别和检测装置设计提供有价值的参考。Periodic signal waveform recognition and parameter measurement are widely used in the field of modern electronic technology.Through the research and analysis of periodic signal waveform,a periodic signal waveform identification and parameter measurement device is designed.Firstly,a program-controlled amplifier is used to accurately amplify the input signals of different amplitudes.Then,the detector circuit is designed based on the LF398 chip.On this basis,the waveform signal is converted into TTL signal by a high-speed comparator.Finally,the Fourier algorithm is used to process the data collected by the ADC,so as to accurately determine the waveform type and display it on LCD.The test results show that the designed device has high measurement accuracy and good real-time performance,which can provide a valuable reference for the design of periodic signal identification and detection device.
