[Stephen] recently wrote in to share his experiments with using the LimeSDR mini to conduct a bit of piracy on the airwaves, and though we can’t immediately think of a legitimate application for ...

A software-defined radio (SDR) terminal promotes programmable realizations of the physical layer functionalities. A lot of research work has been done in applying DSPs and FPGAs to implement the ...

Which RF modulators are best? RF modulators can help to connect old-school technology in an era where many classic devices are being forgotten. VHS players and older gaming consoles are increasingly ...

Despite the need for an IC, this ubiquitous interface between the modulator and audio-video signals has not been reduced to an integrated circuit. The major reasons for that deficiency are the ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...
