ARRANGEMENT FOR PULSE-WIDTH MODULATING AN INPUT SIGNAL |
摘要 |
<p>An arrangement for pulse-width modulating an analog or digital input signal is provided. The non-linear distortion generated in the pulse-width modulator is precompensated by applying a signal with reversed error to the pulse-width modulator. The signal with reversed error is generated by a further pulse-width modulator that receives the input signal and whose output signal is subtracted from twice the input signal. The arrangement may e.g. be used to drive class D audio amplifiers.</p> |
