Question

State three important factors showing the need for translating a low frequency signal into a high frequency wave before transmission.

Answer 1

Three important factors showing the need for translating a low frequency signal into a high frequency wave before transmission is given below :-

1). Low frequency message signals cannot be transmitted to large distances, hence they are modulated on high frequency message signal to transmit this message signals to large distances.

2). If we wish to carry message signals by antenna, signals of higher AF ranges need antennas of heights in certain Kilometers! Hence such long antennas aren't possible.

Therefore, a low frequency signal is translated into a high frequency wave before transmission.

3). While Transmission of low frequency message signal, to avoid any attenuation of signal, a low frequency signal is translated into a high frequency wave before transmission.
