Abstract

This Chapter considers digital signal processing circuits for the digital class-D power amplifier. Special attention is paid to the high quality audio power amplifier. In the digital class-D audio amplifier the dynamics should reach 120 dB, which results in high requirements for the algorithm used and its digital realization. The author proposes a modulator with a noise shaping circuit for the class-D amplifier. Audio signal interpolators are also considered, that allow for an increase in sampling frequency whilst maintaining a substantial separation of signal from noise. The author also presents an original analog power supply voltage fluctuation compensation circuit for the class-D amplifier. The problems of loudspeaker measurements are considered in this Chapter too. The class-D amplifier with digital click modulation is considered as well. Finally, two-way and three-way loudspeaker systems, designed by the author, are presented, for which an input to output signal is digitally processed.
