Abstract
An encoder includes: a phase signal generator that generates and outputs first and second sinusoidal analog signals that are out of phase with each other by 90 degrees, according to a movement of a measurement target; a Lissajous angle calculator that determines a Lissajous angle from the first and second analog signals; and an amplitude adjustor that adjusts an amplitude of only the first analog signal output from the phase signal generator and outputs the adjusted amplitude to the Lissajous angle calculator.
