Passive Harmonic Filter
The simplest of all filters are the ones built using just resistors, capacitors and inductors. Such filters are called passive harmoinc filters, as they are constructed from passive components. In electronics, passive components are those which do not produce energy of their own. They are only capable of dissipating energy (in the case of resistors) or storing energy (in the case of inductors and capacitors). Additionally, their output cannot be altered using a power supply.
Active Harmonic Filter
Active Harmonic filters are named so because they are constructed using active components, or components that add energy to the circuits. Examples of active components include amplifiers, transistors, oscillators, etc. In Active harmonic filters, the most commonly used active components are operational amplifiers or op-amps for short. Amplifiers are used in filter circuits to overcome the drawbacks of passive filters.
