Analysis of Amplitude Modulation and Demodulation in MATLAB Simulink Environment

摘要

This paper presents an approach for studying the amplitude modulation and demodulation. An algorithm for the laboratory exercise and block diagrams for MATLAB Simulink used in it, are presented. This allows students to study the effect of different parameters of the carrier and information signals, of the modulator and demodulator and of the communication channel, on the modulated and demodulated signal.
