Abstract

PURPOSE:To facilitate the zero cross control by deciding a zero point of time when an output digital signal of a digital low pass filter reaches zero with a periodicity by means of an output of an up-down counter. CONSTITUTION:The zero point of time (zero cross) of an output of all up-down counter 80 is not coincident with the zero cross of the output of a digital low pass filter 43. However, if the delay time of the digital low pass filter 43 is recognized in advance, the zero cross of the output of the digital low pass filter 43 is recognized by the output of the up-down counter 80. Thus, the zero cross of the output of the digital low pass filter 43 is decided based on the output of the up-down counter 80. Thus, the zero cross is detected very easily.
