Some Regularities of the Spectral Content of the Responses of Memristive Systems to Sinusoidal Excitation

In the paper, a general first-order memristive system in periodical steady state is analyzed under excitation via sinusoidal signal. Relationships are found between the spectral components of current and memductance which have to be generally fulfilled when generating v-i pinched hysteresis loops of crossing and non-crossing types with nth-order touching at the v-i origin.
