Abstract:
A signal conversion method using three digit symmetric binary numbers (HEN2) as digital data signals, the three digit symmetric binary numbers (HEN2) defined by three digits {n, o, p} each expressing a value {-1, 0, 1} as a one-digit signal, and wherein the digit ""o"" represents zero, the digital data signals comprising a combination of signals in which at least one of two adjacent digits at any digit position of one or more digits of 2-based three digit redundant binary numbers is the digit ""o"", the method including:dividing analog signals into individual sections corresponding to the digital data signals of the three digit symmetric binary numbers (HEN2); andconverting at least one of the digital data signals and analog signals into the other of the digital data signals and the analog signals or mutual converting between the digital data signals and the analog signals.
