ABSTRACT:
A digital processing and comparison indicating apparatus is responsive to an input signal having a value proportional to the quantity to be indicated for displaying a quantity of electrical information in an analog form of decimal notation. A microprocessor compares the value of the input signal with a first plurality of reference values and generates decade enable signals for each one of the first reference values which are less than or equal to the input signal value. The microprocessor also compares the input signal value with a second plurality of reference values and generates units enable signals for each one of the second reference values which are less than or equal to the difference between the input signal value and the value of the largest one of the first reference values for which first enable signals have been generated. The decade and units enable signals drive a display which typically includes a plurality of light emitting diodes for indicating the quantity of the electrical information. This display can have the decades indicating LEDs positioned in a semi-circle or circle and the units indicating LEDs positioned in a straight line for improved readability.
