First-person-view (FPV) flying, by adding a camera, video transmitter, and video goggles to the meat on the ground, is one of the best ways to experience remote-controlled flight. For just a few hu… ...

Upload the code to ESP32 using Arduino, or any other method you prefer. Pay attention on the problems with the analogRead function described in the documentation. Use the sketch in sketch_sample_rate ...

An Arduino-based Spectrum Analyzer that displays real-time audio frequencies on an LED matrix using Fast Fourier Transform (FFT). - Releases · HiraishKumar/Spectrum ...

However, their spectrum analysis abilities are lacking. While these scopes do have a Fast Fourier Transform (FFT) function, it’s limited and nearly useless for RF.

This paper describes a new high speed spectrum analysis technique that tiles a spectral display using a rapid step and dwell spectral sweep. The step and dwell translation operates as a block down ...

This paper belongs to a set of efforts aimed to improve the education of engineering in electronic and telecommunications, based on virtual equipment. It stand on a previous work called Networking ...

Although a spectrum analyzer exhibits better dynamic range and less distortion, the digital oscilloscope FFT provides a cost-effective, space-saving alternative.

The spectrum analyzer uses a fixed number of 1024 samples for each FFT acquisition. That fixed size, combined with an FFT-overlapping process and a FFT rate of 146,484 FFT/s, results in a gap-free ...

GAO Instruments’ USB PC-based digital storage oscilloscope,the Model A0120006, features a 5-in-1 design that integrates a digital scope,logic analyzer, FFT spectrum analyzer, electronic counter, and ...
