Thanks man. You cleared up many things. And I familiar with Fourier analysis:oldwink:

Thank you matteo137 for replying. I'm new to communication systems. Can you tell how exactly side bands carry information? All I know is that the envelope of the carrier wave has the message signal.

Let A= (sin(x) * sin(100x)) + sin(100x).; modulation index is 1; Let B= (sin(x) + sin (100x)); Both of these waves have same frequency and both are amplitude modulated. When passed through an envelope detector, both will give message signal. And B have an advantage of not having any sideband...

I studied the working of the fm transmitter and end up making my own. The first part is amplifier and second (right) part is colpitts oscillator. The circuit works good on simulator. The output is AM modulated wave lying in fm band so it could be detected by radio easily but the circuit is not...
