【Abstract】 This paper introduces the basic structure of a digital power amplifier system, with an in-depth discussion on the implementation of the digital signal processing parts in this system. How to design a simple, useful and low power consumption low pass filter is discussed. Many methods are used in developing this ASIC chip in the consideration of simplicity, low power consumption and easy realization.更多还原
