Abstract
In a wave form signal generating apparatus designed to memorize a desired wave form in the form of a floating point representation for generating a wave form signal based on the memorized wave form, a mantissa and an exponent of a sampling data of the desired wave form are memorized in a predetermined number of digits as a compressed information, and a digit number of the memorized exponent allotted in the predetermined number of digits are further momorized. The memorized exponent is extracted on a basis of the memorized digit number so that the wave form signal is reproduced on a basis of the extracted exponent and the mantissa allotted in the remaining portion of the predetermined number of digits.
