    Hi,
    Could you explain for me why resonance circuit can receive signal at resonance frequency?

    A circuit will actually receive all signals, but it responds differently to signals that are near the resonant frequency of the circuit.

    If the circuit presents a high impedance at its resonant frequency, then signals of that frequency will show a high voltage across that circuit, while signals of other frequencies will show lower voltages.
