µ-Law: Positive Input Values

Notes:

8159 normalized value units correspond to TMAX = 3.17 dBm0.

The character signal corresponding to positive input values between two successive decision values numbered n and n+1 (see column 4)

is 255-n, expressed as a binary number.

The value at the decoder is y0 = x0 = 0 for n = 0, and

, for n = 1, 2,...127.

x128 is a virtual decision value.

Bit 1 is a 0 for negative input values.
