Analog vs. Digital: What’s the Difference? Air temperature, sound loudness,light intensity—in nature, all of these quantities vary smoothly and continuously over a range. Such quantities is called ...

Signals are everywhere, even if you don’t think about them much. They’re what make things like streaming a movie, making a phone call, or listening to music possible. But not all signals are created ...

In a digital world, why bother with analog? Well, sometimes it can still be the right solution. Take, for instance, the analog multiplier (see figure). At its simplest, it’s a circuit that leverages ...

Researchers at RIT have improved the electronics used in communication and radar systems to better process signals using electromagnetic radio waves. This breakthrough could advance computing ...

Wide bandwidth radio transmitters commonly use analog quadrature modulators (AQMs) to convert complex (I + j*Q) baseband signals to radio frequencies (RF). An AQM consists of a local oscillator (LO) ...

We often think of analog computing as a relic of the past, room-sized monstrosities filled with vacuum tubes doing their best to calculate Monte Carlo simulations or orbital velocities. Analog isn’t ...

Several years ago, analog and mixed signal (AMS) content hit a wall. Its contribution to first-time chip failure doubled, and there is no evidence that anything has improved dramatically since then.
