WebModulation is like hiding a code inside the carrier wave. Recall that any wave has three basic properties: 1) Amplitude – the height of the wave. 2) Frequency – a number of waves passing through in a given second. 3) Phase – where the phase is at any given moment. There are different strategies for modulating the carrier wave. WebFrequency modulation synthesis (or FM synthesis) is a form of sound synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator. The … WebApr 7, 2024 · Humans are particularly sensitive to frequency modulation (FM) at slow rates and low carrier frequencies, which are prevalent in speech and music.
