The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...

Harvard SEAS researchers have created an electro-optic digital-to-analog converter that bridges electronic and photonic signals for efficient photonic computing and signal processing. The device is ...

Addressing a major roadblock in next-generation photonic computing and signal processing systems, researchers in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have ...

IBM Research has published a paper discussing a breakthrough in the use of analogue computing for artificial intelligence (AI) calculations. When building AI systems, the data model needs to be ...

In a digital world, why bother with analog? Well, sometimes it can still be the right solution. Take, for instance, the analog multiplier (see figure). At its simplest, it’s a circuit that leverages ...

Scientists from China's Tsinghua University have recently created an all-analog photo-electronic chip. This chip delivers superior performance in computer vision tasks, delivering faster processing ...
