用NIIOS写串口控制程序，控制FPGA及外部D/A,同时产生函数调制信号-Write serial port control program with NIIOS, control FPGA and the external D/A, while producing function modulated signals

脉宽调制 IGBT等电力开关的地开关频率的控制实现-maikuan tiaozhi

主要是信号的调制过程和信号的解调过程 希望对大家有帮助。包括ASK的-Mainly is the signal modulation process and the signal demodulation process We hope to help
