R68-26 Some Techniques for Accuracy Improvement in Analog Computation

Howe has included a variety of valuable information in this paper, the unifying thread being the improvement of precision in analog devices, a topic in which he has long been a leader and innovator. This paper describes 1) precise means of implementing with hardware nonlinear mathematical models involving function generation, multiplication, and division, and 2) techniques of scaling the mathematical model so as to obtain full benefit of the precision available in the analog devices. It is unfortunate that the details of this latest work are somewhat obscured by several errors in the published paper.
