the tuning ofradio and TV receivers is based on resonance the radio and TV receivers have electronic circuits which produce electromagnetic Liberation the frequency of which can be changed by changing the values of the electronic components by the capacity of condenser are the inductance of coil when we want to tune a radio receiver really adjust the values of the electronic components to produce vibrations of frequency equal to that of radio waves which we want to receive in both the frequencies Max resolution and only the energy of signal of the particular frequency is issued from the Waves present in space leaving the signals of other frequencies do not match with the frequency of the receiver circuits signal received is the amplified. in the receiver set. see. it helps you
