We do not transmit low frequency signal to long distances because

The size of the antenna should be comparable to signal wavelength which is unreal solution for a signal of longer wavelength. All statements are true , ,

Effective power radiated by a long wavelength baseband signal would be high. and ,

We want to avoid mixing up signals transmitted by different transmitter simultaneously. are true only and and

Low frequency signal can be sent to long distances by superimposing with a high frequency wave as well. Therefore, the most suitable options will be: are true only are true only

Text Solution

Verified by Experts

The correct answer is:

For low frequency or high wavelength size of antenna required is high.

E P R is low for longer wavelength.

yes we want to avoid mixing up signals transmitted by different transmitter simultaneously.

Low frequency signals sent to long distance by superimposing with high frequency.
