The main role of capacitors is coupling

Coupling capacitors play a significant role in shaping the frequency response of amplifiers. The capacitance value determines the cutoff frequency, which is where the signal begins to attenuate. A larger capacitance allows lower frequencies to pass through more effectively, whereas a smaller capacitance will filter out lower frequencies, potentially impacting audio quality. Choosing the …

How do coupling capacitors work?

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.

Why are coupling capacitors used in analog circuits?

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.

Why does a coupling capacitor block AC and DC signals?

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.
