| 作者简介： Vadim Manassewitsch graduated from Columbia University in 1959. Since 1981, he has worked independently as a consultant, teaching frequency synthesis and designing state-of-the-art synthesizers--his specialty for twenty-seven years.Previously, heserved as an electrical engineer with Manson Laboratories, Inc., as a project engineer with Westrex Company--a division of Litton Industries--and as a member of the technical staff of RCA's Surface Communications Systems Laboratory. He worked as a project engineer for Polarad Electronic Instruments, as a senior member of the technical staff of ITT-I-'s Defense Communications Division, as an engineering consultant for Gl's Electronic Systems Division, and as a senior member of the technical staff of Rockland Systems, Inc. |
