ABSTRACT:
A digital antilogarithmic converter circuit converts digitally logarithmically converted digital information to its antilogarithm. The digital information to be converted is separated into the number to the right of the decimal point and the number to the left of the decimal point. The number less than the decimal point is digitally converted to a linear approximation of its antilogarithm. The number more than decimal point is digitally converted to its antilogarithm. Said linear approximation of the antilogarithm of the number less than the decimal point is digitally multiplied by said antilogarithm of the number more than the decimal point to obtain the antilogarithm of said digital information.
