Abstract:
1. A computer system, comprising: a north bridge chip with a digital-to-analog converter analog power pin and a digital-to-analog converter analog ground pin; a power source coupled to the digital-to-analog converter analog power pin of the north bridge chip; and a resistor-capacitor filter circuit coupled between the power source and the north bridge chip, the resistor-capacitor filter circuit comprising a first resistor and a first capacitor, the first resistor connected between the power source and the digital-to-analog converter analog power pin of the north bridge chip, one end of the first capacitor connected to the digital-to-analog converter analog power pin of the north bridge chip, another end of the first capacitor connected to ground together with the digital-to-analog converter analog ground pin of the north bridge chip.
