Digital PWM amplifier with simulation-based feedback

摘要: Systems and methods for performance improvements in digital switching amplifiers using simulation-based feedback. In one embodiment, a pulse width modulation (PWM) amplifier includes signal processing plant configured to receive process an input audio signal. The also simulator model of signals by the plant. outputs are provided subtractor, output which is then added as may consist modulator power switch, noise shaper, or any other type An analog-to-digital converter (AOC) be convert subtracter. Filtering implemented before after ADC, decimator placed ADC if it oversampling ADC.
