Digital Signal Generator - Producing Common Waveform Signals including Sine, Square, and Triangle Waves

MATLAB Digital Signal Generator capable of generating common waveform signals with graphical user interface, featuring implementation using signal processing algorithms and built-in waveform generation functions

Digital Electronic Organ Function: Each Musical Note Corresponds to a Specific Frequency Signal

A digital electronic organ generates sound by mapping each musical note to a specific frequency signal. It utilizes a digital signal generator to produce sounds at specified frequencies, simulating a virtual keyboard interface with 15 keys labeled A through O. Sound is triggered on mouse press and stops on release. Additionally, the system can generate common waveforms such as sine, square, and triangle waves through a graphical interface for selecting waveform type, frequency, amplitude, and phase parameters. The implementation involves generating digital signals based on user-defined parameters, writing them to the sound card's buffer, and finally outputting the audio through the sound card hardware.
