A '''software-defined radio''' is one in which functions such as tuning, filtering and modulating/demodulating are performed by software rather than hardware. The ease with which this is now possible is due largely to advances in digital electronics.

	An SDR is essentiall a computer attached to an RF front end that performs the usual functions of detection and transmission of radio signals. The key physical component is perhaps the analogue to digital converter that ~~connect~~ the front end to the computer. Processing of the digital output is carried out by CPU.

	* New functions can be ~~added~~ to the ~~radio by changing~~ or ~~adding~~ to the ~~software.~~		The cost of SDR devices is continually falling, and it has recently (as of April 2012) reached the point where price is no longer an obstacle to the beginner. While high quality SDR transceivers still cost over US$1000, a fair quality (but very usable) plug-and-play receive-only software radio can be had for as little as US$11, in the case of the [[RTL2832]].

			Other than a computer, a typical software radio requires these things:

			* An SDR device to convert analogue RF signals into digital data. Wikipedia has a good [[Wikipedia:List of software-defined radios\|list of SDR devices]].
			* A computer program to demodulate the digital data. See the [[List of SDR programs]].
			* An [[Antennas\|antenna]] suitable for receiving RF bands of interest
			* An optional [[Wikipedia:transverter\|transverter]] or downconverter to "move" a section of the RF spectrum into a range the SDR device is able to tune to, if you wish to receive transmissions outside the SDR's native tuning range
