Abstract
An angle measurement system using a magnet and provided with first and second tracks includes an absolute angle calculation unit configured to calculate an absolute angle of a position of the magnet by using a 1-1th digital signal obtained by measuring a magnetic field signal of the first track and converted into a digital signal, a 1-2th digital signal obtained by measuring the magnetic field signal of the first track and converted into a digital signal, a 2-1th digital signal obtained by measuring a magnetic field signal of the second track and converted into a digital signal, and a 2-2th digital signal obtained by measuring the magnetic field signal of the second track and converted into a digital signal.
