Biquinary Code (quibinary code) Definition/Meaning:
A seven-bit weighted code, two bits of which are
used simply to indicate whether or not the coded decimal digit is less than 5.
Four of the remaining five bits are zero the position of the nonzero bit
indicating which of the five possible decimal digits is required. Assuming the
first two bits are 01 if the coded decimal digit is less than 5 and 10
otherwise, then 3, for example, is represented by
0101000
and 9 is represented by
1010000
If, from left to right, the weights 5,0,4, 3, 2, 1, and 0, respectively, are
assigned to the bit positions in a codeword, then the weighted sum of the bits
gives the value of
the decimal digit represented by that codeword.
