PPT-The Resolvers We Use

Geoff Huston APNIC One of those wtf moments This figure was produced as part of some related work that was measuring the additional time penalty that would apply when the name being resolved was signed using DNSSEC. However synchros and resolvers have been and continue to be the preferred type of device where high reliability simplicity and ruggedness are required This is especially true of military and industrial control applications In this article Ken explai How resolvers work resolver sig nal format and how to use resolvers with com mercially available resolvertodigital converters adm tec Advanced Motion Technology Electrical Characteristics Electrically the Rotasyn like a traditional resolver is a tra Geoff .
