    Hi,


    Is Impedence matching and choke inductance both are same?

    How does it effect the LC parallel circuit?

    What is the need of impedance matching inductor for LC parallel circuit?

    The meaning of your question is not clear.

    2. How does it effect the LC parallel circuit
    Also not sure about this question. A parallel resonant circuit will resonate at the frequency at which impedance of the L equals the impedance of the C.

    3. What is the need of impedance matching inductor for LC parallel circuit?
    Same as above, not sure what you want to know. A resonant LC circuit does not need any impedance matching to resonate (other than ZL = ZC

    Thanks for your reply


    I need to know why this inductor is used in the circuit attached below?

    The circuit is alredy having a LC parallel resonant circuit.

    Then what is the need of the inductor that is rounded in black circle
