能用单片机控制DDS芯片实现对输出信号频率/相位的调节，并具有调频、点频、扫频等工作模式，并可以通过液晶显示 -DDS chip can be used to achieve single-chip control of the output signal frequency/phase adjustment, and has FM, point frequency sweep mode, etc., and can be liquid crystal display

matlab code for sweep generation

The load-flow analysis, implemented for both voltage regulation and voltage stability analysis, is performed by using the forward/ backward sweep method. The secant predictor technique is developed for predicting the node voltages which are the
