We usually think of this as a high-frequency effect, but there are important military and commercial avionics requirements that call for conducted susceptibility testing at power-line harmonic and subharmonic

mixers offer an alternative to fundamental mixers in that the LO frequency is at some integer fraction 1/n of the fundamental LO frequency [f.
The main objectives of this paper are to explore different types of complex behaviour, such as subharmonic
oscillations and chaos, in the converters as system parameters are changed.

The effect of the ferroresonance not only described as the jump to a higher frequency state, but also it is given with bifurcations to the subharmonic
