Amplitude modulation (AM) is a modulation technique utilized in electronic communication, most ordinarily for transmitting data by means of a carrier wave. In amplitude modulation, the amplitude that is signal quality of the carrier wave is differed with respect to that of the message signal being transmitted.
Amplitude modulation in MATLAB can be achieved by using the
Syntax : y = ammod(x, Fc, Fs, ini_phase, carramp)
- x : amplitude signal
- Fc : carrier signal frequency
- Fs : sampling frequency
- ini_phase : initial phase in the modulated signal y in radians
- carramp : carrier amplitude of the modulated signal
Returns : amplitude modulated (AM) signal
Example : Amplitude modulation of a sine wave with only 3 parameters.
