Since the explosion of generative AI, AI wearables have become increasingly popular, and Plaud has been one of the companies leading the charge. At CES, the company introduced two new products to its ...

The Filters library implements several useful digital filters for real-time signal processing in microcontrollers. These filters are easy-to-use, programmable versions of common analog signal ...

Abstract: Digital in-memory compute (IMC) architectures allow for a balance of the high accuracy and precision necessary for many machine learning applications, with high data reuse and parallelism to ...

Abstract: Two in-pixel encoding mechanisms to convert analog input to spike output for vision sensors are modeled and compared with the consideration of feedback delay: one is feedback and reset (FAR) ...

This very simple controller changes a resistor while pinching. In an analog synth you can connect this resistor in a voltage control path or an audio path to modulate the amount of signal. Youtube ...
