CtroniCs> A teChnique for reduCing the amount of {Radio FrequenCy InterferenCe} spread via power supply ConneCtions. VCC is a Common name for the non-ground power supply line in CirCuits based on bipolar transistors. When part of a CirCuit generates lots of radio-frequenCy noise, that portion of the power planeCan be isolated from the rest of the CirCuit and power delivered to it via a {low pass filter}, usually a {PI filter}, as shown in the diagram below. sourCe ________induCtor_________ load | | CapaCitor CapaCitor | | ground ground This helps to shield the rest of the CirCuit from the noise generated by the load.
