Ask a question, if in a longer one end of the wire (10 km), a high frequency modulation signal, along a conductor, intervals, decorate a collector, can receive the signal source (electromagnetic waves)?

CodePudding user response:

Of course, must idea impedance matching

CodePudding user response:

3-30 MHZ is high frequency signal transmission of 10 km with coaxial line can, and should add trunk amplifier,

CodePudding user response:

Of course, impedance matching should pay attention to

A few master, will you please add WeChat details? 15840610666

CodePudding user response:

Below 200 KHZ frequency is a transmission capacity, more suitable impedance coupling,
Otherwise all radiation was finished

CodePudding user response:

No clear of the building Lord, must show the frequency of the signal, then consider what kind of wire? Twisted-pair cable can only pass low frequency; Coaxial line can be hundreds of megabytes, higher fiber can be used; If the frequency is very high, the microwaves, should use waveguide mode
