This paper describes a number of computing elements, each combining AD or DA conversion with one or more arithmetic operations or function generation. The elements, termed PHENOs, are claimed to have bandwidth-accuracy products equal to or better than the best linear analog computing components. The authors suggest that PHENOs may be put to good use in two areas. First, in general-purpose hybrid computation, where they represent a logical extension of the MDAC (multiplying digital-to-analog converter) in improving the AD interface. Second, in applications requiring miniaturization, the ability to function in an adverse environment, and the ease of interface with DDA (digital differential analyzer) components, as in airborne and shipboard devices. Both claims appear to be well-founded and merit further investigation by hardware experts in these two fields.
