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 ...

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 ...

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 ...

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 ...

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 ...

Aspects of format conversion have been known and appreciated for some time, due to the frequent need to convert between different video standards. Many of the same techniques that were developed for ...

Here's why I'm asking: I have a Denon AVR 3803 receiver. I like it quite a bit, except for one glaring (IMHO) omission; in order to use my Sennheiser wireless headphones, I have to run both analog and ...

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 ...

Analog-to-digital converters, or ADCs, are somewhat monolithic devices for most users, a black box that you ask nicely for the value on its input, and receive a number in return. For most readers, ...
