Description of 272-1970 1970New IEEE Standard - Inactive-Withdrawn. This standard pertains to computer-type pulse transformers. These pulse transformers are characterized by their use of a square loop core material as defined below with normal operation into the saturation flux density regions and with typical operation using a specifically defined current input pulse. These transformers exploit the memory characteristic of square-loop core material that makes the output pulse dependent upon the immediate history of the core flux. This type of transformer is used in shift registers, memory across switches, memory readout circuits, transformer logic matrices, and other storage-type devices. It is not the purpose of this standard to include large-scale memories. Wherever numerical requirements are indicated, they may be considered as recommended values. Appendix I contains a core analysis, transformer equivalent circuit, and definitions of associated terms. Appendix II contains definitions pertaining mainly to characteristic testing of computer-type pulse transformers.This book also exists in the following packages...Subscription InformationMADCAD.com IEEE Standards subscriptions are annual and access is unlimited concurrency based (number of people that can access the subscription at any given time.

About IEEEIEEE is the world's largest professional association dedicated to advancing technological innovation and excellence for the benefit of humanity. IEEE and its members inspire a global community through IEEE's highly cited publications, conferences, technology standards, and professional and educational activities. IEEE, pronounced "Eye-triple-E," stands for the Institute of Electrical and Electronics Engineers. The association is chartered under this name and it is the full legal name. IEEE creates an environment where members collaborate on world‐changing technologies – from computing and sustainable energy systems, to aerospace, communications, robotics, healthcare, and more. The strategic plan of IEEE is driven by an envisioned future that realizes the full potential of the role IEEE plays in advancing technology for humanity. The IEEE Brand Identity Toolkit explains the basic usage rules for all corporate identity elements and how to utilize them to create a powerful and consistent communications pieces. IEEE is led by a diverse body of elected and appointed volunteer members. The governance structure includes boards for operational areas as well as bodies representing members in the 45 Societies and technical Councils and ten worldwide geographic regions. |
