Discusses the Fields of Interest of Committees and defines the Fields of Communications Technical Committees. With the merger of the IEEE Conununications Division and the IEEE Communications Systems Group into the IEEE ComnunicatioTne chnology Group, a new era has begun for communication engineers. Among the problems that them erger drafters had tos olve was the allocation of fields of interest to the Technical Committees within the new Group. Each committee was assigned to a specialized field, which is allowed to expand, contract, divide, or conlbine, as changing conditions warrant. Any statement of the fields is true only for an interval in our dynamic technology. The following statement provides a general view of the present fields of the Communications Committees. It should be understood that some nmtters presented for comtnit,tee action overlap into the jurisdiction of other committees, both withiu and outside of the Group. These are generally handled by joint action. The statement is intended to serve as a guide for those who wish to work with or present material to a committee. A prospective confercnce paper or a manuscript that may be considered for Transactions publication would be typical items.
