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 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.
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.
A half-wave rectifier with a capacitor-input filter is shown in Below Figure. The filter is simply a capacitor connected from the rectifier output to ground. RL represents the equivalent resistance of a load. We will use the half-wave rectifier to illustrate the basic principle and then expand the concept to full-wave rectification.
The shunt capacitor filters use the property of capacitor which blocks DC and provides low resistance to AC. Thus, AC ripples can bypass through the capacitor. If the value of capacitance of the capacitor is high, then it will offer very low impedance to AC and extremely high impedance to DC.
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.
