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 ...

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 ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) As the Bode plot is the foundation for understanding the operational amplifier (op amp) ...

A digital signal processor is an IC or IP core designed to process signals digitally with efficiency. Analog signals are converted to digital via an analog-to-digital converter before being processed ...

Unless I am mistaken, only analog signals can be regulated through the Windows Volume Control options. You're mistaken. The Windows volume control (for most cards, at least) happens in the digital ...

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 ...

Multimedia applications such as Digital TVs (DTVs), Over the Top (OTT) devices, and Set-Top Boxes (STBs) rely on digital and analog interfaces to transmit & receive audio and video content. The ...

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 ...

Level-crossing analog-to-digital converters (LC-ADCs) represent an innovative approach to signal digitisation that departs from conventional uniform sampling. Instead of capturing signals at fixed ...

Digital video is a method of representing the infinite variations of video signal levels inside a specified limit (e.g. 0mV to 700mV) as a limited number of binary numbers. Figure 1 shows a simplified ...
