When electrical engineers hear the name "Nyquist," they think of what Harry Nyquist is best known for: his Sampling Theorem. Evidence of its importance is everywhere. Products like cell phones, audio ...

A look at the Nyquist sampling theorem. How to deal with aliasing by attenuating signals using low-pass filters (i.e., an antialiasing filter, or AAF). AAF requirements for different ADCs. A deep dive ...

Bravo to Harry Nyquist and Claude Shannon! In the 1920s, these gentlemen created the now-well-known Nyquist theorem, which states that when sampling a signal at discrete intervals, the sampling must ...

Audio functionality plays a critical role in embedded media processing. While audio takes less processing power in general than video processing, it should be considered equally important. In this ...

The current technology trend for Analog-to- Digital Converters (ADCs) is particularly keen on power reduction, together with high-speed performance. The goal of the paper is to demonstrate that both ...

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 concept behind digitizing sound. Working at Bell Labs, Harry Nyquist discovered that it was not necessary to capture the entire analog waveform, and samples of the wave could be taken at various ...
