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.
