说明：  数字下变频技术是数字接收机的核心技术之一，它包括数字混频正交变换、抽取及高效率数字滤波等。(Digital down conversion technology is one of the core technology of digital receiver, which includes digital mixer orthogonal transformation, extraction and high-efficiency filtering.)

注意：本程序中，每点击一次“增加亮度”，图像灰度提升16；每点击一次“降低亮度”，图像灰度降低16。(Note : This procedure, every click an "increase in brightness," gray upgrade 16; Click on each of a "lower brightness," gray lower 16.)
