In 1976, two shaggy-haired college dropouts founded a company called Apple to manufacture personal computers. The company’s prospects looked so poor that the third co-founder relinquished his 10 ...

SDR (software-defined radio) promises operators massive cost reductions. Cognitive radio will soon furnish bandwidth on demand. SDR forces re-evaluation of superhet and direct-conversion technologies.

We are entering a new era of radio technology. A new approach to building radios has made devices like multi-band cell phones and the ubiquitous USB TV receivers that seamlessly flit from frequency to ...

Software-defined radio (SDR) is a radio communication technology that implements conventional hardware components using software. The motivation behind SDR-based systems is reprogrammability and ease ...

Like almost everything else in electronics, radios are becoming processors with software that communicate via a small amount of RF I/O circuitry. Surely, then, the rise of software-defined radio (SDR) ...

We should be able to build a complete, simple direct conversion receiver on a chip using current IC technology. The possible receive frequency would be limited by the IC technology used for the mixers ...

The legendary 6502 microprocessor recently turned 50 years old, and to celebrate this venerable chip which brought affordable computing and video gaming to the masses [AndersBNielsen] decided to put ...
