The difference between digital and analog signals may seem straightforward, but there is a ton of nuance that defines the characteristics of the two systems.

Addressing a major roadblock in next-generation photonic computing and signal processing systems, researchers at the Harvard ...

That analog audio would then get converted to a DS0 digital signal again as it moved around the back-end of the phone network, and then back to analog for the last mile to the customer.

Based on lithium niobate chips, the new device offers a potential replacement for the ubiquitous but energy-intensive digital-to-analog conversion and electro-optic modulation systems used all over ...
