We thank the authors for taking the time to prepare a formal comment on our 1983 paper [1]. Some of the confusion results from our use of b − 1 bits to represent the fractional part of the sign/logarithm instead of b bits as used by Hongyuan and Lee in their comment. The performance curves (Figs. 12-14 of [1]) are plots of output noise variance/output signal variance in units of 2-2 (number of fractional bits). Since there are b − 1 fractional bits, this is equivalent to 22−2b. With this correct interpretation, (48) agrees with Figs. 12-14 in [1].
