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 ...

Bad Fast Fourier Transfer (FFT) data captures can cause you to misunderstand the true performance of your analog-to-digital converter (ADC). Some engineers like to coherently sample and capture data ...

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 ...

What differentiates a mixed-signal printed circuit board design from a purely analog board or a purely digital system? What differentiates a mixed-signal printed circuit board design from a purely ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...

This file type includes high resolution graphics and schematics when applicable. Rob Reeder, Senior System Application Engineer, Analog Devices Analog-to-digital converters (ADCs) are used in a wide ...

How analog signal engineering is performed, in broad strokes. What are the component-selection considerations for new designs? What are VFAs and how are they used? Analog signal engineers specialize ...

A great many industrial sensors — flow, level, temperature, pressure, pH, and the list goes on — produce a 4-20 mA output, but today's factories increasingly need digital inputs via standard field ...

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 ...
