This project started as a personal summer experiment to get hands-on experience with the Arduino IDE, analog signal conditioning, and FFT-based frequency analysis. It takes a raw guitar signal (with ...

It uses the same I2C protocol, as uSDR-Pico. Arduino_uSDX_Pico_FFT - Main code for Ajan-5, it runs at Raspberry Pi Pico, compiled with Arduino IDE (look "Arduino IDE setup and notes" below). Aux - ...

Every machine has its own way of communicating with its operator. Some send status emails, some illuminate, but most of them vibrate and make noise. If it hums happily, that’s usually a good sign, but ...

Modern pulsed radar systems use advanced waveform and modulation characteristics to obtain greater range resolution, enhanced clutter suppression and superior target recognition. Specifically, ...

Many of today's digital oscilloscopes include fast-Fourier-transform (FFT) capability for frequency-domain analysis. This feature is especially valuable for oscilloscope users who have limited or no ...

RF signal observation has evolved from yesteryear’s spectrum analyzer to today’s RF recorder. Swept spectrum analyzers, FFT analyzers, and real-time signal analyzers all had limitations. Today’s RF ...
