For digital PCM systems, this is often measured as SQNR, or signal-to-quantization-noise-ratio which can be express in dB's. The SQNR can be calculated similarly to amplitude decibles as SQNR = 20 log 10 (2 # of bits ) ≈ 6.02 * # of bits dB .

Chapter Five: Digital Audio. 6. Quantizing, Approximation Errors and Sample Size | Page 2. Digital audio editing programs can often use sample sizes above their final product's bit depth. Standard samples sizes of 20-bits, 24-bits, even 32-bit floating-point or long integer samples are now common, used to minimize fractional values and their ...

• To measure the Quantization noise, we should replace the 17 signal bins with the value of the leftmost signal bin (92) to approximate the quantization noise in the signal bins. The integral of this modified PSD from 0 to F s/2 is the noise power, …
