Question

Exercise: Can we use the same communication system in case of transmitting signals across an optical, radio, satellite, or underwater channels? Explain and justify your answer.

Answer 1

They'll not be the same.

Cause each have it's own way of configuration

Lets just think of our old antennas used for black and white TV's

If we use those antennas with the present satellite system will they work??

No definitely not. It's just for an example

Lets consider an optical channel where the transmitted signal will be in the form of light which is not seen to be used in the normal sort of communication and the transmitter, reciever has to change accordingly

And in underwater communications normal electro magnetic waves will not be used and if used there will be so much of delay

So we make use of acoustic waves.This is called as UAC (underground acoustic communication)

And what we dialy see are the radio and satellite communication

Cause the TV signal or the gps are coming from the satellites

The ecosystem change and also the signal frequency change cause the difference between the systems

The radio signals are transmitted by los(line of sight ) or they reach the destination by getting reflected by the earth's surface few times

This is not the case of the signals used in the satellite communication

So a strong no for the question

They all are of different ecosystems and there will definitely be a huge difference between the circuitry and also the signals transmitted
