When it comes to getting signals from an analog world into our computers, most of us don’t give much thought to how the hardware that does the job works. But as it turns out, there are a number of ...

The previous blog discussed how makers can select an A/D converter by understanding the application and how manufacturers optimize a part for that role. Now, what happens when an A/D fires up—how ...

Photonic analog-to-digital converters employ light to sample and digitise high-frequency electrical signals, overcoming the speed and jitter limitations of purely electronic systems. Ultrastable ...

An old algebra teacher used to say, “You have to take what you know and use it to get what you don’t know.” You might say the same thing about converting analog signals into digital. Computers know ...

When the phrase ‘analog to digital conversion’ is used, we tend to assume that the conversion is taking something continuous like sound or video and making it discrete so that digital computers can ...

Engineers have reached a theoretical limit for efficiently converting analog data into digital bits in an emerging computer technology. The future of computing may be analog. The digital design of our ...

In the Op Amp circuit shown in the figure, let Rf = 10kΩ, R1 = 10kΩ, R2 = 20kΩ, R3 = 40kΩ, and R4 = 80kΩ. Obtain the analog output for binary inputs [0000], [0001], [0010], . . . , [1111]. Using this ...

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 ...

Photonic digital-to-analog converters (DACs) harness optical components to transform discrete electronic signals into continuous optical or electrical waveforms. By exploiting properties of light such ...
