X = Arctan(Sin(X)/Cos(X))
According to the real-time amplitude of the sine and cosine signals, the exact position (electrical angle) of the encoder within the sine and cosine period at this moment can be determined through Arctan calculation. Depending on the resolution of the analog-to-digital AD conversion and the quality of the sin-cos signal, each sin-cos cycle can usually be subdivided into 212 to 214 steps. The number of sine and cosine cycles per revolution of the encoder itself, multiplied by the number of subdivision steps of each sine and cosine cycle, constitutes the total resolution per revolution of the sine and cosine encoder after subdivision.
