ABSTRACT

The digital coding of signals for most applications uses a scheme of binary numbers in which only two digits, 0 and 1, are used. This is called a base, or radix, of 2. It is of interest that systems of other bases are used for some more complex mathematical applications, the principal ones being octal (8) and hexadecimal (16). Table 14.1 compares the decimal, binary, and octal counting systems. Note that numbers in the decimal system are equal to the number of items counted, if used for a tabulation.
