When the first USB DTV receivers came out with tuners covering 54–806 MHz, I wondered if any of them could be modified into an inexpensive spectrum analyzer. Thanks to RealTek and some Linux kernel ...

With the ever-growing interest in wireless devices, RF environment simulation is crucial to address the testing and development demand for communication systems and equipment, allowing engineers and ...

A few months ago [Antti Palosaari] discovered cheap USB TV tuners could be used as a software-defined radio. Since then, we’ve seen these TV tuners receive signals from GPS satellites and even the ...

A software-defined radio (SDR) uses a general-purpose computer processor to perform aspects of digital signal processing in place of analog circuit hardware. This allows for greater flexibility in ...
