However in any case with a poor channel (radiated for example) AM suffers heavily from noise interference so FM is preferred. | |

And no one really does anything with AM anymore because it has poor immunity to noise. If you're doing something involving fourier transforms you're probably well beyond the simplicity of AM. | |
