Understanding Amplitude Modulation: Theory and Practice

Amplitude Modulation (AM) alters the carrier signal's amplitude based on message signal information. Learn about AM spectrum, sidebands, modulation schemes, demodulation techniques, and implementation with the DSK6713. Explore simulation, modulator/demodulator setup, and real-time coherent detection using TMS320C6713. Discover the envelope, spectrum, and hands-on applications of AM for signal processing.

Presentation Transcript

  1. Amplitude Modulation

  2. Amplitude Modulation • Amplitude Modulation is a process where the amplitude of a carrier signal is altered according to information in a message signal. • The frequency of the carrier signal is usually much greater than the highest frequency of the input message signal.
