Answer is:
have a receiver transmitter pair
Explanation:
In telecommunications, a?repeater?is an electronic device that receives a signal and retransmits it at a higher level or higher power, or onto the other side of an obstruction, so that the signal can cover longer distances.
Answer is:
periodic signal can be regarded as a superposition of sine wave signals
Explanation:
Fourier analysis of a periodic signal implies periodic signal can be regarded as a superposition of sine wave signals
