| Abstract | Instruments which combine the features of a digital-to-analog conversion and a linear-to-logarithmic scale change usually perform the digital-to-analog conversion first. These instruments are accurate to within five or ten percent over ranges of five or six decades. This thesis presents a method which uses combinatorial logic to perform the linear-to-logarithmic scale change before the digital-to-analog conversion is made (using a ladder of high precision resistors). The reversal of operations results in greatly improved accuracy and range (integral linearities of one percent for ranges as great as 100 octaves). The method is used in the design of a display for a Nuclear Data 160M multi-parameter pulse-height analyzer and is applicable in any system which presents the initial data in a binary register with parallel access. |
