GNU Radio is a free software toolkit for learning about, building, and deploying Software Defined Radios.
It does signal processing in free software. This means you can learn from it and modify it to do new things. The big idea is to give ordinary software people easy access to 'hack' the electromagnetic spectrum, that is, to understand gnu radio presentation at the stanford spectrum conference the radio spectrum and think of clever ways to use it.
GNU Radio offers reconfigurability. Spending $1000 on a piece of radio hardware buys you access to whatever that gnu radio usb device particular radio is configured for. If you have adequate generic hardware, the radio processing can be done in software. Currently only a few forms of radio are duplicated in GNU Radio software, but if you understand the math of a radio transmission system, you can reconfigure your GNU Radio to receive it.

Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
