    Abstract: PURPOSE: A distance measurement signal processing device using a resolver and a method thereof are provided to detect a minimum value and a maximum value of amplified cosine wave signals and sine wave signals of the resolver, thereby accurately detecting a distance. CONSTITUTION: A distance measurement signal processing device using a resolver(10) comprises an amplifying circuit(120), a filter(130), an AD converter(140), and a micro computer(150). The resolver generates first cosine wave signals and first sine wave signals output according to a distance. The amplifying circuit amplifies the first cosine and sine wave signals into second cosine and sine wave signals. The filter removes noise of the amplified second cosine and sine wave signals.
