Question

Why high frequency carrier wave required for transmission of signals?

Answer 1

High frequency carrier waves are needed for effective transmission of information signals because they:



*help in maintaining a practical size for the transmitting antenna and avoid it being very long.



*increase the power that is radiated by the antenna to enhance the transmission range.



*have the capability of converting wide band signals to low band signals.


*transmit many audio signals at a time from the same antenna without mixing them up.
