Abstract This paper investigates the ability of a popular digital voice technique (Adaptive Delta Modulation, ADM/FSK) to operate compatibly in the present Private Land-Mobile Radio Services.

These programs are complicated by benign mutations that cause apparent Hex A deficiency but not TSD. Benign mutations account for only approximately 2% of Jewish and approximately 36% of non-Jewish enzyme-defined carriers. A carrier frequency of 1/53 (n = 1,434) was found in an ongoing prospective analysis of persons...
