Components of a Filter Circuit
The components of a filter circuit are as follows:
- Resistor
- Capacitor
- Inductor
Resistor (R)
Function: The circuit’s current flow is managed by a resistor. It is frequently used in filter circuits to set the time constants in conjunction with capacitors.
Symbol: The symbol of resistor is given below with its representations.
Capacitor (C)
Symbol: The symbol of Capacitor is given below with its representations.
Function: Electrical energy is stored and released by capacitors. Capacitors are frequently employed in filter circuits to pass AC signals while blocking DC signals.
Inductor (L)
Symbol: The symbol of Inductor is given below with its representations.
Function: Inductors store energy in their magnetic fields and resist changes in current. They are frequently employed in filter circuits to allow high-frequency signals to be blocked and low-frequency signals to be passed.
Filter Circuit
An electronic circuit called a filter circuit is made to either pass or block specific frequencies from an electrical signal. It is an essential part of many electrical systems and applications because it shapes a circuit’s frequency response by blocking out undesired frequencies and letting in desired ones. Many electrical devices, including power supply, signal processing applications, audio systems, and communication systems, use filters.
Filters are circuits whose response is dependent on the input voltage’s frequency. Many crucial tasks in a system can be carried out by filter circuits. While resistors, capacitors, and inductors can also be used to create filters, op-amps, resistors, and capacitors are the main components of most filter circuits.
