Without writing a book, the tank circuit (tank) is what is called a tuned circuit. The basic tank circuit has an inductive component (a coil) and a capacitive component (a cap). There are a couple of concepts that you need to get a handle on. A tank has a given "resonance" based on the net inductance and capacitance. It has one frequency that it really likes to run at. That's the resonant frequency (fo). The tank is tuned for that fo. A signal at that frequency that is put into the stage that has a tank filter will cause the tank to "ring" electronically. The signal oscillates in the tank, and, because it's the fo for that tank, some maximum amplitude (gain) will be attained. The signal is then coupled out. Other signals of a slightly different frequency will cause the tank to ring, but not as much. As a signal is put into the stage that is a bit higher or lower than the fo, it causes less oscillation, and it emerges at a lower amplitude. Notice that this applies to signals that are a bit above or a bit lower than the fo. The farther from the fo that a given signal is, the less oscillation it produces in the tank, and the less gain it will be given in that stage. Again (and it's worth repeating), signals both above and below the fo a given distance produce the same oscillation in the tank. That means the tank responds to both sides of the spectrum above and below the fo. Lastly, the tank can be "sharply tuned" or not. In a sharply tuned tank, the signals that are farther from fo cause little tank action, and those right around fo really get a lot of gain. In something less sharpely tuned, there is still a good bit of gain for frequencies higher or lower than the fo. We spoke of the tuning of the tank for a particular fo. Now we have to tune the tank for what is called quality (Q). This speaks to how "tightly" the tank is tuned. And we have to make a trade. If we want a lot gain at fo and little else, high Q is the way to go. There will be a ton of gain at fo, and the gain for frequencies above and below will drop like a rock. In a less tightly tuned tank, there will be better gain for the frequencies around fo, but not as great a gain for the fo itself as there would be in a high Q tank. That's the trade. Narrow tuning yields greater gain for the fo and lower "bandpass" while broader tuning will pass "more frequencies" (have a higher band pass) but with lower gain at and right around the fo than a high Q tank.
Filter is an electronic device which passes specific frequency and attenuates all other.There are 4 types of filters: 1) Highpass - passes only high frequencies 2)Lowpass - passes only low frequencies 3)bandpass-passes only specefic band of frequencies 4)band reject-passes all frequencies excepting desired band
by combining a low-pass filter with a high-pass filter.[1]
in second order filter attenuation to the frequencies in stop band is higher then first order filters.
in series you XL, voltage leads the current, and in Parallel current leads the voltage. so your answer should reflect on this theory.
filter circuits
A low pass filter allows "low" frequencies to pass through a circuit and blocks higher frequencies.
Does not allow high frequencies to pass through the circuit.
The parallel-tuned filter in antenna circuit rejects only the undesired frequencies.
Only frequencies in the pass band range will be allowed through the circuit. Other frequencies will be attenuated based on the RC values picked.
The use of a Capacitor-Resistor (CR) or Resistor-Inductor (RL) in an RLC circuit helps determine the frequency response and filter characteristics of the circuit. The CR combination provides high-pass filter characteristics, allowing higher frequencies to pass through, while the RL combination provides low-pass filter characteristics, allowing lower frequencies to pass through. These components are commonly used in audio crossovers and signal processing applications to control frequency ranges.
A notch filter can be used to filter out specific frequencies, such as 50 Hz, from a signal. This type of filter is designed to attenuate a specific narrow band of frequencies while allowing other frequencies to pass through unaffected.
Without knowing the signals driving such a circuit and the tuning of the tank in the circuit it in not possible to give an exact answer. However assuming the tank is tuned to RF the behavior of the tank and LED should be effectively independent: the tank will respond to the RF in the signal and the LED will respond to the DC in the signal. The behavior would be different if the tank was tuned to low audio frequencies.

A frequency response curve of an acceptor circuit illustrates how the circuit's output amplitude varies with different input frequencies. It typically shows the gain or attenuation of the circuit across a range of frequencies, highlighting its behavior at resonance and in the passband. This curve helps in understanding the circuit's performance, including bandwidth, cutoff frequencies, and how effectively it accepts or rejects signals at various frequencies. Overall, it is a crucial tool for assessing the circuit's filtering characteristics.
