Digital controlled variable frequency oscillator

Claim 1

IN A VARIABLE FREQUENCY OSCILLATOR CIRCUIT HAVING AN OUTPUT FREQUENCY THAT IS DEPENDENT UPON DIGITAL LOGIC INPUT INFORMATION, THE COMBINATION COMPRISING: A PLURALITY OF INPUT MEANS; POLARITY SHIFTING MEANS ELECTRICALLY CONNECTED TO SAID PLURALITY OF INPUT MEANS AND HAVING FIRST, SECOND, THIRD AND FOURTH DIODE MEANS HAVING CATHODE AND ANODE ELECTRODES; FIRST, SECOND AND THIRD BISTABLE MEANS, SAID FIRST BISTABLE MEANS COUPLED TO THE RESPECTIVE CATHODES OF SAID FIRST AND SECOND DIODE MEANS AND SAID SECOND BISTABLE MEANS COUPLED TO THE RESPECTIVE CATHODES OF SAID THIRD AND FOURTH DIODES AND THE BASE OF THE THIRD BISTABLE MEANS, SAID BISTABLE MEANS RESPONSIVE TO RECEIVE A PLURALITY OF PREDETERMINED COMBINATIONS OF DIGITAL VOLTAGE INPUT SIGNALS FOR SHIFTING THE OUTPUT SIGNAL POLARITY IN A PREDETERMINED COMBINATIONS OF SIVE TO EACH COMBINATION OF DIGITAL INPUT VOLTAGES; INTEGRATOR MEANS RESPONSIVE TO THE SIGNAL POLARITY OF SAID POLARITY SHIFTING MEANS; AND VOLTAGE CONTROL OSCILLATOR MEANS COUPLED TO SAID INTEGRATOR MEANS AND RESPONSIVE TO THE POLARITY AND MAGNITUDE OF A SIGNAL FROM SAID INTEGRATOR MEANS.
