该方案采用AD2S1205解码芯片构建了旋变位置解码系统，并设计了相应的硬件电路、软件解码程序，搭建了旋变解码测试系统。实验结果表明，方案所设计的旋变位置解码电路合理，信号时序正确，能够输出稳定可靠的位置信号。(The scheme uses AD2S1205 decoding chip to construct the spin position decoding system. The corresponding hardware circuit and software decoding program are designed, and the spin decoding test system is built. The experimental results show that the rotary position decoding circuit designed in the scheme is reasonable, the signal timing is correct, and the stable and reliable position signal can be output.)
