Abstract：A novel method which is used to produce a digital sinusoidal signal in high-precision is presented、Firstly the basic principle is introduced、And then the error of this method is analysed in detail、Finally the experimental results in a single—phase 4-muhiple inverter are demonstrated、
Keywords：digital signal generator：linear interpolation；SPW M
