1. This is a tuned demodulator that selects the input harmonic closest to the specified Fnom frequency and generates a baseband output signal equal to the instantaneous phase of the selected carrier frequency.
   If there is no analysis harmonic frequency close enough to the Fnom frequency, a warning is issued and the output is 0. The input impedance is infinite. The output impedance is set by Rout, and is limited to a minimum value of 0.1 Ohm. The open circuit output voltage is defined by
   
   where
   
   k represents the value at the analysis harmonic frequency closest to the Fnom value
   0 represents the baseband component of the output voltage.
   All non-baseband output frequency components are 0.
   The maximum phase range of this demodulator is ±180°.
2. In transient and baseband envelope simulations, this model does not generate the expected results because the imaginary part of baseband signals is 0.
