Abstract
Hybrid computation has been with us for a few years, and now techniques, procedures and applica tions are beginning to develop rapidly. We believe great strides can be expected in hybrid simulation now that many equipments are in the field and people are beginning to appreciate the value of bringing the respective qualities of analog and digital computers to bear on individual problems. This column is intended to disseminate information on hybrid simulation and tricks of the hybrid trade. We also hope to stimulate equipment users to provide us with contributions and comments we can publish.
At present the subject of special interest to us in the field of hybrid computation is that of sampling effects at the analog-digital interface. We would en courage anyone who has anything to say on this subject—be it with regard to equipment, technique, program control, or the analysis of sampling-to write to us.
The use of logic elements, gates, flip flops and counters, is foreign to most simulation people, and we are sure tricky circuits have evolved. Although the drive for hybrid came originally from the people with aerospace problems, many developments are occurring in other fields. These should be noted and made available to all who are interested.
As a start this month, we present a short descrip tion by Baker Mitchell of his automatic correlator, which provides nice displays to watch and saves lots of time.
