FREQUENCY SPLITTING SIMULATION
t 481 t 5 80 150 390 80 0 276
Simulation shows frequency splitting which occurs when the primary and secondary tuned circuits are magnetically coupled together.  The coupling coefficient can be changed to study the effect of coupling  amount on the upper and lower split frequencies.
