This step-by-step amplitude modulation process ensures that low-frequency audio signals can be transmitted over long distances by riding on high-frequency carrier waves. Below ... building and ...

[ChrisJ7903] has created two Ardiuno programs for reading Victron solar controller telemetry data advertised via BLE. If you’re interested in what it takes to use an ESP32 to sniff Bluetooth Low ...

thanks to a quirk of science that lets broadcasters bounce radio waves off the ionosphere, it can reach thousands of miles, penetrating rough terrain and geopolitical boundaries. How did this ...

Sometimes we have to do engineering works or there is something happening that could involve a partial or complete loss of services.

Abstract: This paper assessed the efficacy of Gaussian Min-imum Shift Keying (GMSK) modulation in detecting SpO2 utilizing Software-Defined Radio (SDR) and Universal Software Radio Peripheral (USRP).
