"WebFrom a circuit perspective, stray/parasitic capacitance acts like an unwanted capacitor along an interconnect or in a circuit. This explains the bandlimiting behavior; the function of parasitic capacitance is to filter some signal away from an interconnect or circuit, and this increases at higher frequencies, creating low-pass filter behavior.
