High Quality Content by WIKIPEDIA articles! The mathematics of radio engineering is a pleasant and very useful subject. This article is an attempt to provide a reasonably comprehensive summary of this almost limitless topic. While the ideas have historically taken some getting used to, one of the goals here is to present them in a more readable way than is normally found in rigorous texts. Almost the entire subject is based on complex analysis, which has a reputation for being rather beautiful. Also, it is a relief to most people when they hear that this does not necessarily mean "complicated". In fact, some of the old names for the complex plane are still occasionally used today, such as the Gauss plane and the Argand plane.
