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.
