DDS的特点就是改变频率时相位是连续的，AD9833里面有一段话也说明了这一点：The input to the phase accumulator can be selected either from the FREQ0 register or FREQ1 register, and is controlled by the FSELECT bit. NCOs inherently generate continuous phase signals, thus avoiding any output discontinuity when switching between frequencies. 请问您是如何更改频率控制字的？
