Oversampling D/A conversion systems are widely used in digital audio equipment to improve reproduction audio signal quality. The authors have developed an 8-times oversampling digital filter CMOS LSI with higher performance and several other functions in a chip. 8-times oversampling (interpolation) digital FIR (Finite Impulse Response) filtering, digital de-emphasis IIR (Infinite Impulse Response) filtering and digital attenuation are the main functions of this LSI. This paper describes the system construction and performance and the digital signal processing of the developed digital filter LSI.
