The paper derives formulas for the mean-squared error distortion and resulting signal-to-noise (SNR) ratio of a fixed-rate scalar quantizer designed optimally in the minimum mean-squared error sense for a Gaussian density with the standard deviation σ<SUB>p</SUB> when it is mismatched to a Laplacian density with the standard deviation σ<SUB>p</SUB>. The SNR formulas, based on the key parameter and Bennett's integral, are found accurate for a wide range of 수식. Also an upper bound to the SNR is derived, which becomes tighter with increasing rate R and indicates that the SNR behaves asymptotically as 수식 ㏈.
