Hello.
I've learn that it is better to have different value capacitors between power and GND to countermeasure various frequency range.
But...as you know, parallel connection of capacitances results in equivalent one capacitance of series-sum, so two capacitors actually plays as single bigger one.
Mathematically, I don't see the reason to use two capacitors instead of one single bigger one.
Can somebody clarify this confusion?
