The usual method of bringing analog inputs into a microprocessor is to use an analog-to-digital converter (ADC). Here are some tips for selecting such a part and calibrating it to fit your needs. In ...
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 ...
Confused by analog-to-digital converter specifications? Here's a primer to help you decipher them and make the right decisions for your project. Although manufacturers use common terms to describe ...
Back in the day where the microprocessor was our standard building block, we tended to concentrate on computation and processing of data and not so much on I/O. Simply put there were a lot of things ...
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 design and optimisation of analog-digital converters (ADCs) and digital-analog converters (DACs) play a pivotal role in modern electronic systems, bridging the gap between the analog real world ...
NuForce introduced the DAC-9 Digital-to-Analog Converter, Preamplifier and Headphone Amplifier offering six digital inputs to cover the full range of current digital formats. Each input feeds a pair ...
Can a $249 digital-to-analog converter/headphone amplifier deliver state-of-the-art sound? The Audiophiliac listens to the AudioQuest DragonFly to find out. Steve Guttenberg Former contributor ...
[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 ...
