For nonuniform quantizer, such as μ-law and A-law, the SNR for low-level signals increases at the expense of the SNR for high-level signals.
举一反三
- For both m-law and A-law, the signal-to-noise (SNR) of low-level and high-level signals improve with the increasing m and A.
- 中国大学MOOC: For both m-law and A-law, the signal-to-noise (SNR) of low-level and high-level signals improve with the increasing m and A.
