Saturable core pulse width modulator

Claim 1

A PULSE WIDTH MODULATOR COMPRISING A BISTABLE MAGNETIC CORE CAPABLE OF ASSUMING TWO STATES OF MAGNETIC SATURATION, SAID CORE INCLUDING A SINGLE INPUT WINDING, A FIRST CONTROL WINDING, A SECOND CONTROL WINDING, A SOURCE OF POSITIVE D.-C. VOLTAGE, A SOURCE OF NEGATIVE D.-C. VOLTAGE, SAID FIRST CONTROL WINDING RESPONSIVE TO THE CHANGE OF SAID CORE FROM ONE STATE OF SATURATION TO THE OTHER STATE OF SATURATION FOR GENERATING A FIRST CONTROL SIGNAL, SAID SECOND CONTROL WINDING RESPONSIVE TO THE CHANGE OF SAID CORE FROM SAID OTHER STATE OF SATURATION TO SAID ONE STATE OF SATURATION FOR GENERATING A SECOND CONTROL SIGNAL, A FIRST TRANSISTOR SWITCH INCLUDING A BASE, AN EMITTER, AND A COLLECTOR, SAID BASE BEING CONNECTED TO SAID FIRST CONTROL WINDING FOR RENDERING SAID FIRST TRANSISTOR CONDUCTIVE IN RESPONSE TO SAID FIRST CONTROL SIGNAL, SAID EMITTER BEING CONNECTED TO A JUNCTION BETWEEN SAID SIGNAL INPUT WINDING AND SAID FIRST CONTROL WINDING, SAID COLLECTOR BEING CONNECTED TO SAID POSITIVE SOURCE; SAID FIRST TRANSISTOR WHEN CONDUCTIVE APPLYING A FIRST SIGNAL TO SAID SIGNAL INPUT WINDING, SECOND TRANSISTOR SWITCH INCLUDING A SECOND BASE, A SECOND EMITTER AND A SECOND COLLECTOR, SAID SECOND BASE BEING CONNECTED TO SAID SECOND CONTROL WINDING FOR RENDERING SAID SECOND TRANSISTOR CONDUCTIVE IN RESPONSE TO SAID SECOND CONTROL SIGNAL, SAID SECOND EMITTER BEING CONNECTED TO A JUNCTION BETWEEN SAID NEGATIVE SOURCE AND SAID SECOND CONTROL WINDING, SAID SECOND COLLECTOR BEING CONNECTED TO THE JUNCTION BETWEEN SAID SIGNAL INPUT WINDING AND SAID FIRST CONTROL WINDING AND THUS TO SAID FIRST EMITTER, SAID SECOND TRANSISTOR WHEN CONDUCTIVE APPLYING A SECOND SIGNAL COMPLEMENTARY TO SAID FIRST SIGNAL TO SAID SINGLE INPUT WINDING, SAID CORE CHANGING FROM SAID ONE STATE OF SATURATION TO SAID OTHER STATE OF SATURATION AT A RATE WHICH IS A FUNCTION OF THE AMPLITUDE OF SAID FIRST SIGNAL, SAID CORE CHANGING FROM SAID OTHER STATE OF SATURATION TO SAID FIRST STATE OF SATURATION AT A RATE WHICH IS A FUNCTION OF THE AMPLITUDE OF SAID SECOND SIGNAL, SAID JUNCTION BETWEEN THE SIGNAL INPUT WINDING AND THE FIRST CONTROL WINDING PROVIDING AN OUTPUT WHICH IS RESPONSIVE TO EACH CHANGE OF STATE OF SAID CORE FOR GENERATING AN OUTPUT PULSE, WHEREBY AN OUTPUT PULSE IS PROVIDED THE WIDTH OF WHICH IS A FUNCTION OF THE RATE OF EACH CHANGE AND WHEREIN THE AMPLITUDE MODULATOR OF THE OUTPUT PULSE IS ELIMINATED.
