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.

Variable analog function generator

An analog switching system having fan-out for switching a plurality of inputs coupled to analog signal sources with respect to a plurality of outputs coupled to analog signal destinations. A three stage switch matrix includes input, middle and output switch blocks with each block having a plurality of analog switch means and latching means. Any one input terminal of a switch block may be connected to any one or more of the output terminals of that block. A matrix controller coupled to each of the switch blocks addresses each switch block and actuates at least one of the latching means to provide a connection assignment for at least one of the analog switching means.
