设计含异步清零和同步时钟使能的加法计数器

已经正式出版，西安电子科技大学出版社，FPGA设计及应用，作者褚振勇(Has been officially published, Xi' an University of Electronic Science and Technology Publishing House, FPGA design and application, the author Zhezhengyong)

The AGC is a smart programmable gain amplifier (PGA). The amplifier gain is adjusted based upon the input signal level so that the output is at a specified Target Gain. The AGC can be configured to be either a mono or stereo input / output component. For illustration purposes, the following discussion will highlight the stereo configuration.
