The transformer could be used as a mixer in the RF frequency range. I'm feeding 120 volts through the 600 ohm resistor and measuring the primary and secondary. The voltage drop across the 600 ohm resistor only leaves a millvolt signal on the transformer.
With 1 volt input the signal is dead.
with 100KHz input the primary receives 1 volt. The reactance is well above the 600 ohms in series.
We normally use 600 ohms in audio systems and 50 ohms in RF so I changed the generator to 50 ohms.
I changed the time base to show the signal is sine wave, no distortion. Take note of the turns ratio and inductance ratio.
