SQNR
A metric for measuring quantization precision, defined as the ratio of original signal power to quantization error power, expressed in decibels (dB). A higher SQNR indicates less quantization noise.
Timeline (last 90 days)
SQNR (signal-to-quantization-noise ratio) is defined as the ratio of original signal power to quantization error power, usually expressed in decibels (dB).
For uniform quantization, the theoretical SQNR ≈ 6.02 × bit count + 1.76 dB, so the theoretical upper limit is about 49.9 dB for INT8 and about 25.8 dB for INT4.
