Research and Design of Digital Synthesizer Based on MATLAB

Timbre and flexibility are two significant indexes of synthesis; in order to combine both of their features, based on methods of FM synthesis and sampling intervals synthesis, to realize a new method of digital-synthesis by time-domain wave envelope processing and frequency-domain modulation to a key period wave taking from guitar. The results of synthesis can sound better performance, also have a certain flexibility in design and application. It is achieved the designing in computer via MATLAB, provide a reference to the designing of digital synthesizer for portable and small equipment.
