ABSTRACT:
A generalized Gray code converter includes a decimal-binary to intermediate-binary converter and an intermediate-binary to Gray code converter. The decimal-binary to intermediate-binary converter is operable to convert a sequence of sets of electrical signals encoded in decimal-binary format (decimal-binary sequence) to a sequence of sets of electrical signals encoded in intermediate-binary format (intermediate sequence). The intermediate-binary to Gray code converter, connected to the decimal-binary to intermediate-binary converter, is operable to convert the intermediate sequence to a sequence of sets of electrical signals encoded in Gray code-binary format (Gray code sequence).
