Abstract:
1. A digital system for converting an analog expression for a quantity, H, to a multilevel digital expression, comprising: at least one input terminal for receiving said analog expression, representing said quantity, H; an adder a keyboard means for entering into said system selected numbers, L and n being parameters of a multilevel digital system, where 1/L is a base of n digits, 1/L, 1/L a register connected to said keyboard for storing n and L; said register arranged for entering and storing an arbitrary reference value, V, in said register where V is any value that is larger than any anticipated value of H; a divider connected to said register and keyboard arranged for successively dividing V by L, said division by L repeated n times wherein each division by L generates one more digit represented at a respective output terminal of said divider where n is an integer selected to provide that V/L a multiplier connected to output terminals of the divider and to the keyboard means for entering a respective level value, m said multiplier accumulating at output terminals of said multiplier a totality of said generated multi level digits as said each multilevel digit is newly created and added to the accumulation registered by the multiplier; a comparator arranged for successively comparing said accumulation of said multilevel digits to analog expression of H to where a difference of said accumulation subtracted from H, is less than said tolerated error in the value of H converted to said multilevel digital format.
