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 ...

The MindWave DAC is a software-based digital-to-analog converter that delivers high-precision analog signals at low frequencies within a scalable and cost-effective design. Our DAC is designed 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, ...

"Upgradeitis" is a term bandied about the audio world to describe the desire to buy new gear that you technically don't need. Sure, an extra HDMI input or a slightly better room correction system ...

A Raspberry Pi 5 has the ability to capture video via attached cameras and access the Internet using wired and wireless protocols, all while driving a pair of personal computer displays. However, if ...

The usual method of bringing analog inputs into a microprocessor is to use an analog-to-digital converter (ADC). Here are some tips for selecting such a part and calibrating it to fit your needs. In ...

Ready to convert your older analog audio to more portable digital formats? Here’s how to make it happen. By J. D. Biersdorfer A huge amount of the world’s audio has been digitized, but many veterans ...

Designers of digital systems are familiar with implementing the 'leftovers' of their digital design by using FPGAs and CPLDs to glue together various processors, memories, and standard function ...

More and more of today’s modern industrial systems are requiring high accuracy. Traditionally, the test and measurement market has been the primary driver of highly accurate signal chain components, ...
