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 ...

Many power ICs use frequency jitter, which spreads a control signal's spectrum, to control EMI (electromagnetic interference). If you need to add frequency jitter to power ICs that control three-phase ...

In the circuit in Figure 1, the comparator's output will go high if input B is greater than input A. It will fall when input B is less than input A. If the comparator and input signal sources are ...

Clocks are the heartbeats of embedded systems, providing timing references and synchronization between components, subsystems, and entire systems. Incorrect clock signal amplitudes and timing can ...

Races, missed next-state values due to long paths, and metastability can result from corrupted clock signals. This post describes the challenges of clock network and clock jitter analysis in more ...

A while back we saw a logic clock that used the alternating current frequency from the power grid to keep time. We asked for information on your projects that use this method and we got a lot of ...

OK, here's a little electronics mystery. I have an old (2000s) wall clock in my bedroom that I had to take apart just now because a battery leaked in it (dang Duracells....). The clock takes two AA ...

The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall clock ...
