FM Modulation/de-modulation Circuit : 7 Steps (with ...
https://www.instructables.com/FM-Modulationde-modulation-Circuit/
In a nutshell, for FM signals, the frequency of the signal varies based on the voltage level coming in. So a high voltage gives a high frequency, and vice versa. With AM, the frequency stays the same, but the amplitude goes high or low depending on the input voltage. As you will see, this circuit actually uses both.

Two FM modulation circuit diagrams to share. FM, namely: frequency modulation, frequency modulation, refers to the modulation method in which the frequency of the high-frequency carrier changes with the modulating signal. The amplitude of FM remains unchanged. As the receiving distance increases, the amplitude decreases due to propagation attenuation, and the degree of …

2 km FM Transmitter Circuit Diagram, Working and Applications
https://electronicshub.org/fm-transmitter-circuit/
FM Transmitter Circuit Principle: FM transmission is done by the process of audio pre amplification, modulation and then transmission. Here we have adapted the same formula by first amplifying the audio signal, generating a carrier signal using an oscillating and then modulating the carrier signal with the amplified audio signal.
