A capacitor that is used to filter out a certain frequency otherwise series of frequencies from an electronic circuit is known as the filter capacitor. Generally, a capacitor filters out the signals which have a low frequency. The frequency value of these signals is near to 0Hz, these are also known as DC signals.
For low-frequency signals, the capacitor offers extremely high resistance and for high-frequency signals, it proves less resistance. So it acts as a high pass filter to allow high-frequency signals and block low-frequency signals. In a circuit, both AC and DC signals can be used several times.
The following circuit is the capacitive high-pass filter. In this, signals like DC or low frequency will be blocked. Generally, a ceramic capacitor with 0.1µF value can be placed following the signal that includes both the AC and DC signals. This capacitor allows AC and filters out the Dc component.
A capacitor is used to filter out the DC signal. This can be done by connecting the capacitor in series in the circuit. The following circuit is the capacitive high-pass filter. In this, signals like DC or low frequency will be blocked.
Components involved in filter Circuit A filter circuit comprises of generally inductor and capacitor. The inductor allows DC only to pass through it and capacitor allows AC only to pass through it. Thus, a circuit formed by the combination of inductors and capacitors can effectively filter the signal according to the application.
Generally, a capacitor filters out the signals which have a low frequency. The frequency value of these signals is near to 0Hz, these are also known as DC signals. So this capacitor is used to filter unwanted frequencies.
