各級稅率-
It is based on the platform of hardware of fpga, dsp, d / a to realize the concise and full - function digital variable bit rate test signal resource. this paper discuss the ways of full digital if and realize it, certainly the ways to realize the carrier frequency, sub - carrier frequency and variable bit rates with dds technology is also presented
本課題是以fpga 、 dsp 、 d / a為硬體平臺，設計實現了結構簡明，功能完整的全數字可變速率測試信號源，討論並實現了中頻頻段如何實現全數字的方法以及用dds技術實現載波頻率，副載波頻率，碼速率的方法。
