A salt-grain-sized neural implant can record and transmit brain activity wirelessly for extended periods. Researchers at Cornell University, working with collaborators, have created an extremely small ...

Abstract: This brief presents a low-power, high-data-rate impulse-radio ultra-wideband (IR-UWB) transmitter that integrates a two-dimensional differential pulse position modulation (2D-DPPM) with time ...

Abstract: This study examines improvements to the Asynchronous Pulse Code Multiple Access protocol designed to facilitate multi-frame message transmission ...

Sometimes, when an audio component dies, the root cause is something electrical. Other times, the issue instead ends up being fundamentally mechanical. Delta sigma modulation-based digital-to-analog ...

OpenAI CEO Sam Altman sent a memo to his staffers outlining a "code red" effort to improve ChatGPT, according to multiple reports. The company is facing increasingly stiff competition from rivals like ...

Google’s own ‘code red’ response to ChatGPT has started paying off. Google’s own ‘code red’ response to ChatGPT has started paying off. is a London-based reporter at The Verge covering all things AI ...

Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...
