Every modern computer has a microprocessor in it, but not many have a digital signal processor (DSP). Since the CPU is a digital device, it clearly processes digital data, so you might wonder what the ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

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 ...

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 ...

The analysis of RF and microwave signals in the frequency domain used to be the forte of the spectrum analyzer, but now it’s become a choice between signal analyzers and digital oscilloscopes. How did ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

Most wireless headphones and speakers rely on some type of digital signal processing. Here's what you need to know about DSP—and why it's hard to avoid. I've been a contributing editor for PCMag since ...

Many of the best video cables on the market today were designed primarily for use in the digital domain; but can a digital cable really perform well as an analog cable? Can an analog cable be used as ...
