whatever decouples the noise from your circuit. you look at noise frequency..then tell.............you need to make sure that the capacitor has HIGH impedance for the signals of your circuit....but LOW impedance for the unwanted signals which it will "flush" away to ground
Decoupling capacitors are used to cancel circuit noise and vary from AC supply (50/60 Hz) to RF (Ghz / Thz ) .It's very dificult tell you "range".There are a lot of variables , most important working frequency.
