Communication plays an indispensable part in several facets of the human existence. To communicate or transmit information over a long distance, modulation is required. This paper presents amplitude modulation (A.M) in which the amplitude of the carrier is altered in accordance to the input (message) signal, while we keep the frequency constant. The modulated signal (carrier) contains the spectral components which is in the frequency domain analysis. The key concept and principle of A.M are presented with several illustrations with MATLAB and Simulink model to make it easier to understand.
