| Abstract: | 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. |
