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 ...

Spectrum Analyzer with Arduino: An Arduino Due and a PC give you the frequency response of any device, filter or amplifier, up to 100kHz.

First, you need to prepare the hardware setup according to the scheme and upload the code to ESP32. Then, you need to run the Streamlit app and connect to the ESP32. The app will automatically connect ...

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 ...

This audio spectrum analyzer utilizes an ARM7 LPC2138 microcontroller to create an FFT algorithm while performing digital signal processing without the use of special DSP processor. This audio ...

Abstract: 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 ...

RF and EMI engineers spend a great deal of time looking and plots of frequency and amplitude. Depending on the application, you may need a traditional swept spectrum analyzer for continuous signals ...

Abstract: The estimated accuracy of phase and frequency of all phase FFT spectrum analysis and its correction techniques are high[1-3], for its perfect characteristic of inhibiting the spectrum ...

EE’s electronic test instrument coverage achieved critical mass in the mid-1980s, including a spectrum analyzer story in the August 1986 issue and subsequent August issues into the 1990s and beyond.
