Step-by-step explanation
Attenuation is the loss of signal strength in networking cables or connections.
Transducers are used in electronic communications systems to convert signals of various physical forms to electronic signals, and vice versa.
Demodulation is defined as extracting the original information-carrying signal from a modulated carrier wave.
Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction.
