ABSTRACT:
In a personal computer wherein a digital circuit and an analog circuit commonly use the same power supply, a low-pass filter is inserted in a power supply line of an analog circuit to remove switching noise generated from the digital circuit or the power supply, thereby preventing the switching noise from being supplied to the analog circuit and hence output image and sound quality from being degraded due to interference by the switching noise in the analog circuit.
