Could you please show me the way with which the decoupling capacitor should be connected to a circuit? You can take any example on your choice.

Thanks in advance.
 

Hello my friend
How are you ?
It is simple
See here please:

Again Hi
as we know , when the last stage , is busy with signal amplification , the DC current will have change due to the amplified signal . and as we know , the wire has an equivalent circuit with complex impedance what means that it is kind of a high order filter . and if the frequency of operation of your circuit is high , the DC voltage of first step will be pretty unstable . with this circuit that called "Decoupling " we have isolated the DC voltage of first stage from second stage ( from it's supply) . my mean is that , the capacitor will do opposition with the instantaneous and fast changes . and with the series resistor , in fact , we did it : the instantaneous changes will lockout across it.
Best Wishes
