Audio signals cannot be transferred directly into space.Why?
What's the process required to make the transmission of audio signals possible???
Are there any types???
Dear Student
Kindly find the answer of your asked query.
Audio signals can be directly transmitted through the space this is because the optimum length of the radio antenna is half or quarter of a wavelength. And typical wavelength of audio signals is around few hundreds killometers, hence very large antennas are required.
So to transmit the audio signal, it is modulated with the carrier wave having radio frequency. This is frequency modulation.
Other than this amplitude modulation and phase modulation are also used.

Hope this information will clear your doubt about communication.
