ABSTRACT:
There is disclosed a bifrequency output device. The bifrequency output device comprises Josephson junctions, a resistor for generating a given voltage in response to a pulse current which is supplied from the outside, and a time delay element for delaying the voltage generated by the resistor during a given time period and then providing it to the superconducting elements, so that the bifrequency output device outputs different low frequency and low voltage and high frequency and high voltage depending on the initial condition of the superconducting elements constituting the Josephson junctions and the voltage with a given delay time which is induced to the superconducting elements.
