| Abstract: | In communication, carrier frequency lower than 30KHzis seldom employed. This paper, however. demonstrates some properties of signal transmission on very-low-frequency, discusses the key points of receiving such signals, and especially solves the problem of 50 Hzdisturbance by designing a wave trap. As an example, very-low-frequency signal transmission is applied in petroleum industry to detecting obstacles in oil line, The general construction of very-low-frequeney receiver is also given. |
