摘要
介绍了立体声数字功率放大器系统的基本结构,深入讨论了数字功率放大器的数字信号处理部分的实现原理。最后重点介绍了ASIC实现时滤波器的设计方法,以及为了减少复杂度、功耗而采取的一系列措施。
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.
