Modulation 1 FM

In telecommunications and signal processing, frequency modulation ( FM ) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. A major advantage of FM in a communications circuit, compared for example with AM , is the possibility of improved Signal-to-noise ratio
(SNR). Compared with an optimum AM
scheme, FM typically has poorer SNR below a certain signal level called the noise threshold, but above a higher level – the full improvement or full quieting threshold – the SNR is much improved over AM.

OK so you've lifted some well described explanation of FM modulation expounding it's virtues against AM. You then create an AM circuit ?????

Yeah i dont get how the circuit shows this.
