The frequency spectrum of pulse width modulated signals
The determination of the frequency spectrum of a pulse width modulated (PWM) signal with general band-limited input x(t) has been an open problem for many years. We describe a new approach that givesExpand

High-fidelity PWM inverter for digital audio amplification: Spectral analysis, real-time DSP implementation, and results
A complete digital audio amplifier has been developed, implemented and tested. The process is entirely computational, and the output load and filter are the only analog components in the system. TheExpand
