I couldn't afford to buy a DX7, being a poor college student. I had to be happy fantasizing about the DX7. I sat in the univerity computer lab for hours printing out graphs of fm waveforms that I created on the computer, and I wished that I had a DX7 so that I could hear those waveforms. I researched how fm synthesis might be done with analog electronics. But everything I could find in the university library was about fm in radio signals. The subject of fm in the electrical engineering manuals dealt entirely with modulating a carrier wave with a signal whose frequency was below the carrier frequency. But fm synthesis in the DX7 was performed by modulating the carrier with a higher frequency than the carrier. I have still never seen a VCO (voltage controlled oscillator) circuit that will perform fm on its carrier signal.
The time domain signals are illustrated above, and the corresponding spectra are shown below (spectrum amplitudes in ).In and frequency modulation synthesis (or FM synthesis) is a form of where the of a simple waveform is changed by it with a modulating frequency that is also in the audio range, resulting in a more complex waveform and a different-sounding tone.

The frequency of an oscillator is distorted in accordance with the amplitude of a modulating signal.
As the amount of frequency modulation increases, the sound becomes progressively more complex.
Creates both harmonic and inharmonic sounds.
How does FM synthesis relate to Bessel?
The harmonic distribution of a simple sine wave modulated by another sine wave signal can be represented with Bessel functions.
Note that at I = 0 (i.e.
