Musical Signal Processing with LabVIEW -- Modulation Synthesis

Abstract

Amplitude modulation (AM) and frequency modulation (FM) are familiar types of communications systems. When the modulating frequency is in the audio range, AM (also called ring modulation) produces interesting special effects by shifting the source signal spectrum, and can be used to raise or lower the pitch of an instrument or voice. FM creates rich, time-varying spectra that can be designed to emulate the sound of many different musical instruments. Learn about the mathematics of AM and FM, and learn how to implement these modulation schemes as audio signal processors and music synthesizers in LabVIEW. This course is part of the series "Musical Signal Processing with LabVIEW".
