Example types with companding
The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:
Companding allowed acceptable audio performance with only seven bits per PCM sample in this original T1/D1 system. (18 words)
This is equivalent to using a non-linear ADC as in a T-carrier telephone system that implements A-law or μ-law companding. (24 words)
Implementation There are three ways of implementing a μ-law algorithm: ;Analog: Use an amplifier with non-linear gain to achieve companding entirely in the analog domain. (27 words)
Graph of μ-law & A-law algorithms An A-law algorithm is a standard companding algorithm, used in European 8-bit PCM digital communications systems to optimize, i.e., modify, the dynamic range of an analog signal for digitizing. (39 words)
The logarithmic companding laws are consistent with human hearing perception in that a low-amplitude noise is heard along a low-amplitude speech signal but is masked by a high-amplitude one. (32 words)
Implementation There are three ways of implementing a μ-law algorithm: ;Analog: Use an amplifier with non-linear gain to achieve companding entirely in the analog domain. (27 words)
