When I studied the resonant frequency of an RLC circuit in series and parallel, there was the definition that I read in books that the imaginary part of the total impedance of the circuit has to be equal to zero and the frequency where that happens is the resonant frequency. I'm fine with that, but there can be multiple transfer functions in a circuit depending on what output signal you choose, so for every transfer function there is 1 or more frequency values that generates the maximum value (amplitude) of the function. So is there 1 (or more) resonant frequency for every specific transfer function? Or are those values not resonant frequencies?
