Creating a video signal from a computer, a job that once required significant extra hardware, is now a done deal with a typical modern microcontroller. We’ve shown you more NTSC, PAL, and VGA… ...

[Leigh] is a HAM operator (you may know him as wa5znu). He is familiar with a signal visualization tool called a waterfall which plots signal strength and frequency over time. He wanted to build hi… ...

The output signal can also be obtained from signal images rather than the fundamental signal, allowing operation well above the 125 MHz clock frequency. Perhaps we’ll look at these applications in a ...

Rather than purchasing a universal remote he designed a system complete with infrared “babel fish” signal translator, named after the language translation fish from Hitchhiker’s Guide to the ...

Raspberry Pi and Arduino MCU are used as Signal Processing Unit (SPU). Data acquisition and signal averaging will done in signal processing unit.
