The market for audio applications and devices has significantly grown over the last couple of years. Applications such as smart speakers, Bluetooth speakers, smartphones, and voice-controlled ...

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 ...

Basic review of how the different kinds of analog-to-ditital converters wor, with a sidebar relating them to appropriate applications. ADCs quantize time-varying analog voltages into a sequence of ...

Regular Contributor Dave Van Ess from Cypress Semiconductor reviews ADC noise sources, design implicatons of inherent noise, and ways to minimize circuit-generated noise. 1. Quantization is noise. 2.

It is not surprising that the world around us is getting more and more digitized. One reason might be that manipulation, storage, and usage of data in digital form is more convenient and easier than ...

In part 1 of this pair of articles, we ran SPICE noise simulations on a simple second order lowpass filter. We saw that there is something fundamental about the ‘hold’ that the filter’s capacitor ...

We casually speak of digital audio, often referring to it as AES audio, perhaps AES3 (for the number of the AES standard), or by an older term AES/EBU. But what exactly is this AES3 signal? Here’s the ...

It’s a counterintuitive result that you might need to add noise to an input signal to get the full benefits from oversampling in analog to digital conversion. [Paul Allen] steps us through a simple ...
