I am wondering if i need to take into account the input and output impedance when finding a filter circuit frequency from it's transfer function. The previous LC filter i designed took into account the input and output impedance which result in -6dB+ even at low frequency when i simulated it. I suspect i might be missing a concept to understand why it is -6db even before the -3db drop at the cutoff frequency. Thank you for your time.
