摘　　要：运用同频相关理论设计了一种同频相关分析仪，该仪器用模拟电路实现了两正弦函数互相关函数的测量，可在动态测试过程中从混有噪声的信号源中把有用信号提取出来。Based on the same frequency and interrelating principle in the signal analysing theory, this article designs a kind of same frequency analytical instrument, and realizes the measurement of mutual interrelating function of two sine signalls by simulated circuit. This instrument can be used to abstract useful signals from signal resoure mixed with noises.
