ABSTRACT:
N expansion bits are added to the LSB side of original data of m bits and thereby expanded data of (m+n) bits is obtained. In the case of m.ltoreq.n, each bit of original data of m bits is repeatedly assigned to the LSB side of original data. In the case of m>n, n bits on the MSB side of the original data of m bits are added to the LSB side of original data. Since the bit values of expansion bits vary corresponding to the values of the original data, a bit expansion can be smoothly performed in the full range.
