Abstract

PURPOSE:The pulse-width modulated signal with the pulse width which corresponds to tuning frequency information is DA-converted to simplify the setting of the attenuation amount of the filter for obtaining a tuning DC voltage, thereby making it possible to shorten a delay time with the constitution of the filter simplified.
