本作品以MSP430单片机为核心， 基于DDS原理，通过查表方式输出步进量为10HZ，频率为100HZ~2KHZ的正弦波。两路被测信号通过过零比较、异或和低通滤波整流，实现了对相位差的测量，误差小于(This works with MSP430 microcontroller as the core, based on DDS principle, by look-up table output step sizes for the 10HZ, frequency of 100HZ ~ 2KHZ sine wave. Two by the signal zero-crossing comparator, XOR, rectification and low-pass filtering, the realization of the phase of the measurement error is less than)

1. 本研究利用 PCA 对可见-近红外（450～1 000 nm）、可见光（450～780 nm）和近红外（780～1 000 nm）光谱区域的苹果高光谱图像数据进行降维，获得 PC 图像，通过对 PC 图像进行分析，确定可用于分割损伤和正常区域的有效光谱区域，对比分析几个光谱区域的 PCA 的效果。(but currently no practical system for detecting blood spots and dirt stains exists. In order to obtain maximum throughput, processing speeds of over 85,000 eggs per hour are common. The demanding requirements placed on the human workers result in two types of grading errors)

对于学习分析时序很有帮助，是一款逻辑分析仪的软件，很有用的。(Timing analysis is useful for learning, is a logic analyzer software, very useful.)
