Uniform quantization: Destination SNR
nDefine the destination SNR by



that is by using q=2v and [dB]s
n
n
n
n
nNote that for 8 bits this yields
n
nHowever this is an upper bound and in practice Sx<<1 and typically signals follow LP-type PDF as for speech the Laplace-pdf:
n
nTherefore non-uniform sampling is frequently applied
