High-resolution encoding process for an integrated optical analog-to-digital converter A technique is described for extending the resolution of an integrated optical multi- interferometer guided-wave analog-to-digital converter. The optical o... Styer,D David - 《Optical Engineering》 被引量: 90发...
In an analogue to digital converter a binary counter controls, through a decoder circuit and a plurality of current generators, the charge on the condenser which is compared with the signal voltage to obtain a signal when they are equal. The converter has a characteristic approximating to a ...
An analog-to-digital converter (ADC) ( 112 ) for sampling high speed video signals includes Pre-amplifiers ( 502, 504, 506 ) electrically coupled to Post-amplifiers ( 508, 510, 512 ) that are electrically coupled to output latches ( 514, 517, 519, 521, 523, 525, and 527 ). A ...
digital signal into an analog signal, especially into an electrical signal whose voltage reflects the digital values. Digital-to-analog converters are commonly used to convert digital media for playback on analog devices, such as speakers, headphones, and older televisions. Also calledD/A converter...
