In previous installments of the AudioFile, we've talked about basic PCM audio, which encodes audio into a series of numbers that a computer can play or manipulate. We've also discussed the process 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 ...

[Daniel Garcia] sent us a quick tutorial he put together demonstrating how to use an ATmega168 to perform analog to digital conversions. This timely tutorial would make for a nice complimentary ...

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 ...

Photonic analog-to-digital conversion (ADC) represents a paradigm shift in signal processing by leveraging the inherent advantages of photonic devices to digitise analog signals. The approach aims to ...

While we all went through intensive course work in engineering school studying analog-to-digital converters (ADC), operational amplifiers (Op Amp), digital-to-analog converters (DAC) and other ...

A great many industrial sensors — flow, level, temperature, pressure, pH, and the list goes on — produce a 4-20 mA output, but today's factories increasingly need digital inputs via standard field ...

Nobody will cry when the static dies. “Analog” television — those grainy, sometimes static-filled broadcasts — will end on Feb. 17, 2009. That’s the date that the Federal Communications Commission has ...

Comcast has postponed the date it will begin moving channels from analog to digital. Subscribers have until Nov. 16 to obtain the equipment necessary to continue seeing channels such as MSNBC, the ...

Making sound with digital logic usually calls for a Digital to Analog converter. Building one can be very simple, and the sound quality out of an R-2R Ladder is actually pretty good. In the last ...
