８０９８单片机数字比相系统东南大学机械工程系黄寿荣，黄家贤，赵继军机械系统传动链误差测试一般要用分频比相方法。传统的比相方法是模拟比相，用记录仪记录测试结果，并以它作为误差分析的依据。这类比相仪电路复杂、体积大、精度低、柔性差，难以实现信号在线处理和... 8098 single-chip digital phase comparison system Southeast University Department of Mechanical Engineering Huang Shou-rong, Huang Jiaxian, Zhao Jijun mechanical system transmission chain error test generally use the frequency-division ratio method. The traditional method of phase comparison is to simulate phase contrast, record the test results with a recorder, and use it as the basis for error analysis. Such analog phase instrument circuit complexity, large size, low accuracy, poor flexibility, difficult to achieve online signal processing and ...
