-         * This table is a an ordered list of noise values computed by the
-         * formula from the spec sheet such that the index into the table
-         * starting at 43 or 45 is the SNR value in db. There are duplicate noise
-         * value entries at the beginning because the SNR varies more than
-         * 1 db for a change of 1 digit in noise at very small values of noise.
-         *
-         * Examples from SNR_EQ table:
-         * noise SNR
-         *   0    43
