Operating Principle:

The working of tuned voltage amplifier may be understood by considering a radio frequency signal, to be amplified applied at the input of the amplifier. The resonant frequency of the tuned circuit is made equal to the frequency of the input signal by changing the value of capacitor (C) and inductor (L). When the frequency of the tuned circuit becomes equal to that of the input signal a large signal appears across the output terminals.

If the input signal is a complex wave (i.e. it contains many frequency components.) in that case the frequency with input frequency equal to the resonant frequency will be amplified. And all the other frequencies will be rejected by the tuned circuit.
