Converting message amplitude values into a pulse sequence corresponding to a binary permutation code

Claim 1

A CIRCUIT ARRANGEMENT FOR CONVERTING AMPLITUDE VALUES (ANALOG VALUES) OF A MESSAGE INTO AN IMPULSE SEQUENCE CORRESPONDING TO A BINARY PERMUTATION CODE, WITH THE AID OF A SERIES CIRCUIT INCLUDING RESISTORS WHICH EXHIBIT FLIP PROPERTIES AND THE RESISTANCE VALUES OF WHICH DEPEND UPON THE CURRENT FLOWING THERETHROUGH, SAID RESISTORS BEING TRAVERSED BY AN ANALOG CURRENT CORRESPONDING TO THE AMPLITUDE VALUE WHICH IS TO BE CONVERTED, WHEREBY THE INDIVIDUAL FLIP RESISTORS FLIP AT DIFFERENT VALUES OF THE ANALOG CURRENT FROM A CONDITION OF LOW RESISTANCE TO A CONDITION OF HIGHER RESISTANCE AND VICE VERSA, COMPRISING A PLURALITY OF FLIP RESISTORS CORRESPONDING IN NUMBER TO THE DESIRED NUMBER OF AMPLITUDE STAGES, MEANS FOR ARRANGING SAID FLIP RESISTORS IN AT LEAST TWO MUTUALLY PARALLEL EXTENDING SERIES CIRCUITS A PLURALITY OF DIFFERENCE AMPLIFIERS CORRESPONDING IN NUMBER AT LEAST TO THE NUMBER OF PLACES OF THE CODE FOR COMPARING THE VOLTAGES OCCURING AT THE FLIP RESISTORS OF TWO ROWS, AND AT THE OUTPUTS OF WHICH APPEARS THE IMPULSE SEQUENCE CORRESPONDING TO A BINARY PERMUTATION CODE.
