What are the applications of excess 3 code?

Excess-3 code is a non-weighted code used for decimal numeral representation in digital systems. Its primary applications include error detection and correction in digital circuits and simplifying the design of arithmetic operations in binary-coded decimal (BCD) systems. Additionally, it is employed in some digital display systems and calculators, where it helps in preventing certain types of errors during data processing. Overall, Excess-3 code enhances reliability and efficiency in electronic systems that handle decimal data.
