PROBLEM TO BE SOLVED: To enhance conversion performance by obtaining a digital angle output using a negative feedback system including a resolver within a closed loop. SOLUTION: In this digital conversion method for an analog signal, the digital angle outputψis obtained using the negative feedback system 10 including the resolver 1 within the closed loop, in a method for inputting a two-phase sinusoidal wave signal 2 into an R/D conversion part 3, and for converting an input rotational angleθinto the digital angle outputψ.
