T2F
- T2F子函数，在做傅里叶变换时调用。我一开始编程序时忘了加它，结果WARN ME 说未定义T2F。-T2F subroutine, called when doing Fourier transform. I started to compile the program forgot to add it, and the result is undefined WARN ME said T2F.
83390078DDS
- DDS的工作原理是以数控振荡器的方式产生频率、相位可控制的正弦波。电路一般包括基准时钟、频率累加器、相位累加器、幅度/相位转换电路、D/A转换器和低通滤波器（LPF）。频率累加器对输入信号进行累加运算，产生频率控制数据X（frequency data或相位步进量）。相位累加器由N位全加器和N位累加寄存器级联而成，对代表频率的2进制码进行累加运算，是典型的反馈电路，产生累加结果Y。幅度/相位转换电路实质上是一个波形寄存器，以供查表使用。读出的数据送入D/A转换器和低通滤波器。-DDS works
