摘要:
An A/D converter apparatus comprises: a sampling signal generating means to generate an oversampling signal and an internal sampling signal; a converter means to convert an input analog signal into a digital signal in synchronism with the oversampling signal; and a decimator means to perform a specified decimation on the digital signal in synchronism with the internal sampling signal; whereby the sampling signal generating means maintains the frequencies of the oversampling signal and the internal sampling signal in a specified relationship.
