Without them it would be impossible to make an oscillator stay on frequency , or to enable a receiver to select a desired signal and suppress all others . Tuning circuits are combina- tions of inductance , capacitance , and resistance ...

The exact frequency of resonance - or anti- resonance , as it is often called in referring to parallel circuits - can now be found from equation ( 4 ) by substituting the values of X and Xc in terms of frequency , and solving for the ...
