CRANE-84005
An analog-to-digital converter is a device that converts a voltage to a digital number. A variety of analog-to-digital converters has evolved recently, but there is a strong demand for faster converter devices.

Naval Surface Warfare Center, Crane Division (NSWC Crane), has developed and patented a photonic analog-to-digital converter that transforms a continuous physical quantity (voltage) to a digital number that represents the quantity's amplitude. This technology provides higher sampling rates, allowing conversion of higher frequency analog signals using a larger bandwidth and a technique for incorporating the architecture in electronic devices.

Advantages:
-Provides higher sampling rates
-Converts higher frequency analog signals at a high speed

Potential Applications:
-Music recordings
-Digital signal processing
-Scientific instruments
