I have seen power rails bypassed with parallel capacitors which are at least an order of magnitude apart in capacitance value. From what I understand, one capacitor filters high frequency noise and the other filters low frequency noise.
1. Which capacitor does what? The low value capacitor filters low frequency noise?
2. What physical property of a capacitor is responsible for the difference in frequency response?
