		<description><![CDATA[This section goes into detail on some of the more technical topics relating to wireless microphones.

Gain Structure
Just as in audio systems, gain structure and noise are extremely important for radio frequency devices.  In particular, RF systems are very susceptable to various kinds of noise and interference, including thermal noise, intermodulation, distortion, and other kinds [...]]]></description>

		<description><![CDATA[Frequency coordination is essential to the proper function of wireless systems.  Not only must channels be sufficiently spaced apart, but they must also be checked to ensure that they will not interfere with each other if the RF signals become distorted.  This phenomenon, commonly referred to as \emph{Intermodulation distortion}, occurs when signals pass through nonlinear devices such as amplifiers and receiver circuits.  Finally, channels must be selected to avoid television stations (both analog and digital), and also two-way radio systems operating in certain cities.]]></description>

		<description><![CDATA[Antennas are passive electrical devices that convert electromagnetic radiation into electrical signals, and vice versa.  Both transmitters and receivers require antennas to operate.  Transmitters typically have small &#8220;whip&#8221; antennas mounted on them, and receivers usually have a connector on the rear to attach an external antenna.  There are a number of types [...]]]></description>
