Which component is used in LC filter?
LC filters refer to circuits consisting of a combination of inductors (L) and capacitors (C) to cut or pass specific frequency bands of an electric signal. Capacitors block DC currents but pass AC more easily at higher frequencies.
Which are the advantages of LC filter?
It has a very low ripple factor as compared to series inductor filter and shunt capacitor filter. It has very good load regulation. It has no loading effect on the rectifier and power transformer. It has better voltage regulation than that of π filter.
What is another name of LC filter?
It is also known as inductor input filter, choke input filter, L input or LC-section.
What are the advantages and disadvantages of LC oscillator?
The benefits of LC oscillators are phase stability and low susceptibility to noise. LC oscillators have a higher Q factor than Relaxation oscillators. However, they have lower tuning range and higher cost compare to Relaxtion oscillators.
What are the applications of LC oscillators?
The LC circuit is used to select or generate a specific frequency signal. The application of LC circuits is reflected in many electronic devices, especially radio devices, such as transmitters, radio receivers and television receivers, amplifiers, oscillators, filters, tuners and frequency mixers.
How is LC filter related to inductor filter?
LC Filter In inductor filter, the ripple factor is directly proportional to the load resistance. On the other hand in a capacitor filter, it is varying inversely with the load resistance. Hence if we combine the inductor filter with the capacitor the ripple factor will become almost independent of the load filter.
How are capacitors and inductors used in filter circuits?
A capacitor allows A.C only and inductor allows D.C only to pass. So a suitable L and C network can effectively filter out the A.C component from rectified wave. A filter circuit consists of passive circuit elements i.e, inductors, capacitors, resistors and their combination.

What is the load resistance of a CLC filter?
From theory of capacitor filter, V DC = V m –I DC /4fC=396-0.1/ (4*50*10*10 -6 )=346V. For a given CLC filter, the operating frequency is 50Hz and 10µF capacitors used. The load resistance is 3460Ω with an inductance of 10henry.
