Based on the Newnes Pocket Book, this Windows-based software presents a reference on all aspects of radio and communications engineering. Wave principles and the decibel scale, instrumentation and power supplies, equipment types and encryption methods, connectors and interfaces, are all included on this disk. Each topic is presented as point-and-click pop-ups. The Factfinder can by searched by keyword, chapter heading, or by pages sequentially, or even compiled into user-defined folders. Each of the Newnes Factfinders builds up into a coherent data library, and the user has the option of searching for a topic or item of data across all the Factfinders they have purchased.
