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 ...

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 ...

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 ...

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 ...

Real-time spectrum analysis of audio signals using FPGA-based Fast Fourier Transform implementation on the Zynq-7000 SoC platform. This project implements a real-time audio spectrum analyzer using the ...

Abstract: 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 ...

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 ...

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 ...

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 ...
