Quantization Noise (cont)
•The higher the number of quantization levels, the lower the quantization noise.
–For a low number of levels (~<6 bits), the quantization noise can be heard as correlated with the input signal
–For larger number of bits, the quantization noise can be modeled as an independent Gaussian noise source.
•maxSNR=20*log10(2k) (ex, 16bit sound has a dynamic range (or best case SNR of 96dB)
