C.10.9.1.5 Waveform Bits Allocated and Waveform Sample Interpretation

Waveform Bits Allocated (5400,1004) specifies the number of bits allocated for each sample, and Waveform Sample Interpretation (5400,1006) specifies the data representation of each waveform sample. Waveform Bits Allocated shall be a multiple of 8. These data elements are related, and their defined terms are specified in Table C.10-10.

Table C.10-10

Waveform Bits Allocated and Waveform Sample Interpretation

Waveform Bits Allocated - Defined Terms Waveform Sample Interpretation - Defined Terms Waveform Sample Interpretation Meaning
8 SB signed 8 bit linear
UB unsigned 8 bit linear
MB 8 bit mu-law (in accordance with ITU-T Recommendation G.711)
AB 8 bit A-law (in accordance with ITU-T Recommendation G.711)
16 SS signed 16 bit linear
US unsigned 16 bit linear

Notes: 1. The set of valid values from within this table may be constrained by definition of the IOD (see Section A.34).2. mu-law and A-law encoding is without the alternate bit inversion used for PCM transmission through the telephone network.

This representation also applies to the Channel Minimum and Maximum Data Values, and Waveform Padding Value.
