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.
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.
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.
In this circuit, the capacitor works like a high pass filter that allows high frequencies and blocks direct current. Similarly, they can also work as a low pass filte r to allow DC and block AC. Here the capacitor is connected in parallel with the component instead of connecting in series. This circuit is a high-frequency capacitive filter.
The capacitor is a reactive component used in analog electronic filters due to the function of the capacitor’s impedance frequency. Depending on the frequency of the capacitor that affects the signal. This property is therefore widely used in the design of filters.
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.
