How do smaller capacitors filter out higher frequencies than larger …
I commonly see 0.1 µF used on IC pins for decoupling. I occasionally see 0.01 µF and 0.001 µF capacitors used for filtering out higher frequencies. Is that incorrect, because I thought the impedance If practical capacitors were purely capacitive, then indeed, a larger capacitor would do an even better (or at least "as good") job of filtering …
