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 ...

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 ...

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 ...

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 ...

All analog-to-digital converters (ADCs) have a certain amount ofinput-referred noise. In most cases,less input noise is better. There are some cases, however, where inputnoise can actually be helpful ...

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 ...

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 ...
