Different types of modulations can be performed – amplitude modulation, phase modulation / frequency modulation. In amplitude modulation, the information is encoded as variations in the amplitude of a carrier signal. Demodulation of an amplitude modulated signal, involves extraction of envelope of the modulated signal. Other MathWorks country Then by multiplying the phase modulated carrier with a local oscillator at the carrier frequency we get: $$\sin(2\pi f_c t + \phi(t))\cos(2\pi f_c t)$$.
