This paper details the development of a monophonic audio synthesizer utilizing Field-Programmable Gate Arrays (FPGAs) to achieve precise digital synthesis of sinusoidal waveforms. The significance lies in its application for professional audio, where accurate waveform generation is critical for various electronic functions. Key results indicate that the FPGA-based synthesizer successfully approximates sinusoidal waveforms at specific frequencies, demonstrating both digital and analog implementation capabilities.
Achieving high-fidelity audio synthesis on FPGAs could redefine standards in professional audio applications.
Signal synthesis is used in every aspect of the electronics world, where sinusoidal waveforms are used to perform functions such as clocking, signal transmission, feedback controls, and other applications. Digital synthesis is the method of approximating sinusoidal waveforms using digital logic, where the waveform is approximated to an accurate degree at a specific frequency which can be either implemented digitally or converted into the analog domain for use elsewhere. This project details the creation of a digital synthesizer commonly used for professional audio applications through the implementation of hardware in an FPGA.
