ABSTRACT:
A variable analog function generator which is independent of an external computer during the time that it generates at least one predetermined output function of at least one input variable. The output function is expressed in terms of hybrid variables each having an analog portion and a digital portion. The function generator has a first dedicated memory which is loaded during set up time with data related to breakpoints defining the input variable. A second dedicated memory is loaded during set up time with tables of values defining the digital portion. During function generation, the analog portions are generated in response to (1) the input variable and (2) the data related to the breakpoints which is accessed in parallel from the first dedicated memory. The output function is generated in response to (1) the analog portions and (2) the tables of values accessed from the second dedicated memory.
