Abstract
With the apparatus described, the logarithmic slope of a signal may be changed so that a relatively flat signal has its scale expanded to make full use of the available voltage range. To do so the supplied logarithmic signal is clamped to a selected voltage level and then linearly amplified to develop an output signal having a logarithmic scale different from that of the supplied signal.
