The lowest frequency of an LC low-pass filter is zero, i.e. DC.
sounds same to me.maybe you meant advantage of LC filter over RC filter
For a series a.c. circuit, resonance occurs when the inductive reactance is equal to the capacitive reactance. You can work out the frequency at which this occurs by inserting the variables into the following equation:XL = XC
They are not suitable for use as extremely low-frequency oscillators because the inductors and capacitors would be large in size, heavy, and costly to manufacture.
1/(2 Pi sqrt(LC))
A local oscillator is used in a superheterodyne radio circuit for example.The incoming radio frequency is mixed with an internal local oscillator circuit to generate a new intermediate frequency (IF) .The local oscillator usually runs at a frequency of 470kHz and is generated by an inductor and capacitor(LC oscillator)
Out = In / (1 + 2 s csi / omega + ( s / omega )2) where s is Laplace variable [s/rad] csi is the damping factor omega is the resonating frequency If you want to calculate the Vout/Vin ratio: ----L---- | C | ---------- csi = 0 (damping comes from resistive component) omega = 1/sqrt(LC)
In LC filter , Bleeder resistance is connected in Parallel with the load to maintain the minimum current through the choke and so the performance of the Filter improves.
depends on the oscillator and its purpose
by removing the old filter

The difference between an RC and LC is that the frequency - determining device in the RC oscillator is not a tank circuit. LC can operate with A or C biasing, while RC can only operate with A.
Self-tuning feedback
Another type of sine-wave generator uses inductors and capacitors for its frequency-determining network. This type is known as the LC OSCILLATOR. LC oscillators, which use tank circuits, are commonly used for the higher radio frequencies. They are not suitable for use as extremely low-frequency oscillators because the inductors and capacitors would be large in size, heavy, and costly to manufacture.

IF YOU RUN IT W/O A FILTER, THE INDOOR COIL BECOMES THE FILTER AND CONTINUES TO FILTER UNTILL IT BECOMES PLUGGED AND FAILS COMPLETELY. LC
LC are connected in parallel combination to short out signals too high or too low in frequency from getting to the load.FYI:Series LC circuits give minimum impedance at resonance, while parallel LC (“tank”) circuits give maximum impedance at their resonant frequency.The LC circuit behaves as an electronic resonator, which are the key component in many applications. Oscillators Mixers Graphics tablets Filters Electronic article surveillance & TunersFor example: a capacitor/inductor oscillator acts as the tuner for the radio.The sine wave that matches that particular frequency will get amplified by the resonator, and all of the other frequencies will be ignored. In a radio, either the capacitor or the inductor in the resonator is adjustable. This is how you "tune in" different stations on the radio :)In a nutshell: A series resonant circuit provides voltage magnification and a parallel resonant circuit provides current magnification.
