Abstract
Hereinafter disclosed is methodology and apparatus for converting wide dynamic amplitude range digital data recorded in floating point digital word form, comprising a binary coded mantissa and a binary coded exponent, to an analog signal, or oscillogram, of compressed dynamic amplitude range. The digital word, occupying a number of binary bit positions, is, in algebraic form, .+-.AG.sup..sup.-E ; where A represents the mantissa, or argument, G represents the base, or radix, of the number system used and E represents the exponent. Since the base G is constant at 8, for example, the only binary bits that need to be recorded are those representing the mantissa A and the exponent E. In reconverting the digital data to analog form for making an oscillogram, or wiggle trace, it is proposed to compress the dynamic range and, yet, at the same time avoid introducing serious distortion. Apparatus for performing the aforesaid changes, among other things, is disclosed.
