As a result of significant sign attenuation inherent in wire, transmission around distances greater than a few kilometres demands the use of frequently spaced repeaters to amplify, restore, and retransmit the signal. Transmission traces also demand impedance matching within the transmitter or receiver to be able to minimize echo-producing reflections. https://trentonohyqj.digiblogbox.com/53702397/fascination-about-gulf-telecommunication-awards
