Abstract
The data acquisition portion of a data signal processing system has a nonnear data compression and conversion arrangement and a data decompression and scaling arrangement. The non-linear data compression and conversion arrangement employs graduated reference voltage levels provided by resistors having graduated, unequal values, such as values being related as a geometric progression. The graduated form of the reference voltage levels provide a form of data compression wherein large value and small value measurements will have essentially the same fractional resolution. The data decompression and scaling arrangement can decompress previously compressed digital signals and limit the digital data width of such signals in systems which have input dynamic range requirements greater than their output resolution requirements.
