Abstract
An information handling system includes a digital circuit having a first terminal connected to a first voltage reference, and a second terminal connected to a second voltage reference. The digital circuit is configured to be coupled to a radio device. The system also includes a band pass filter having a first terminal connected to the first voltage reference, and a second terminal connected to the second voltage reference. The bandpass filter is configured to produce a low impedance response, to reduce a radio frequency noise generated at a specific frequency band of the band pass filter, and to reduce a radio frequency interference produced by the digital circuit and received at the radio device.
