How to find coupling and decoupling capacitor values?
In the case of (AC) coupling capacitors you want the most optimum capacitor for your signal frequencies. In practice the actual value of the capacitor does not matter too much as long as it is "enough". For example, to suppress a supply ripple of 100 Hz, a 10 nF capacitor isn''t going to help much. A 100 uF capacitor will help but so will …
