Here’s a detailed look into the construction of coupling capacitors: The dielectric is an insulating material placed between the two conductive plates. Its primary function is to increase the capacitor’s capacitance by reducing the electric field’s strength between the plates.
Its construction is very simple. Just a dielectric is present in between the parallel plate capacitors. This coupling capacitor is good at obtaining final output as AC signals. There exist decoupling capacitors as well in which the output generated is consisting of DC signals. Hence coupling capacitors are preferred in analog circuits.
When the AC signals supply from the microphone to the o/p device, then the DC signal cannot pass because this signal gives the power to the parts in the circuit. On the o/p end, we get the AC signal. So a coupling capacitor is placed between two circuits so that AC signals supplies while the DC signal is blocked.
The capacitor is a basic component in both the electronic circuits like analog & digital. These are used in a variety of applications like coupling, filtering, timing, and de-coupling. The coupling type allows AC components and blocks DC components.
The main function of this capacitor is to block the DC signal and allows the AC signal from one circuit to another. These capacitors are used in various circuits where AC signals are used to be output whereas DC signals are simply used to provide power to circuit components but they should not come out in the output.
A decoupling capacitor is used to decouple one part of an electrical network (circuit) from another. In this context, it is a capacitor that blocks DC while allowing AC to pass through. In analog circuits, it is used to connect two circuits such that only the AC signal from the first circuit can pass through to the next.
