This article introduces a high-precision digital phase-shifted sine wave signal generator based on FPGA and digital frequency synthesis technology, using VHDL to compile a program and download it to Xilinx\'s SpartanⅡ series XC2S100E-6PQ208 FPAG chip, and adding simple peripheral circuits. The device can generate two sine wave signals with digitally preset and adjustable frequency, phase, and amplitude, with a phase difference range of 0 to 359° and a step of 1°.
