Synthesis of optimal periodic signals with phase modulation
frequency) of the sidebands will follow the basic rule:where k is the order of the sideband and generally ranges from 0 to the modulation index + 2Thus, for example, a carrier frequency of 400Hz with a modulator frequency of 100Hz and modulation index of 1, will produce a spectrum with frequencies as shown in the following table:The sidebands would in this case seem like harmonics of a 100Hz tone, with partials at:100Hz, 200Hz, 300Hz, 400Hz, 500Hz, 600Hz, 700HzIn order to grasp the implementation of Frequency Modulation in CLM (or in any other system for that matter), it is important to understand something about phase increment.

Designed to provide a powerful, flexible sampling engine for modular synthesis, the ASSIMIL8OR Multi-Timbral Phase Modulation Sampler module is the latest incarnation of Dave Rossum’s decades-long pioneering of affordable professional sampling technology.

Let's say you have a carrier frequency of 200 Hz and a modulator frequency of 100 Hz; coverings occur starting with the third undertone (which is also 100 Hz and the following 200, 300, etc.), which result in amplifications and suppressions according to phase length.The advantage of FM synthesis over additive synthesis (the simple addition of sine waves) is that you only need two oscillators to make a rich and complex sound (you just have to change the frequency and especially the amplitude of the modulator!).
