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 ...

Analog-to-digital converters (ADC) sample an analog signal and convert it to a series of digital values. Most data packages in real-world applications are transmitted using analog signals. In order to ...

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 ...

Oscilloscopes provide critical signal visibility for debugging, testing, and ensuring that electronic systems match developers’ imaginations. Specifying when the oscilloscope captures information ...

Beamforming is used for directional signal transmission and reception with the versatility to change both amplitude and phase to help regulate power needs and steer the beam in the intended direction.

Today it seems that everything electronic is digital—a reasonable assumption considering it’s hard to find a turnable knob anywhere and values are displayed in digits everywhere. The underlying ...

Analog design has never been easy. Engineers can spend their entire careers focused just on phase-locked loops (PLLs), because to get them right the functionality of circuits need to be understood in ...

EIM Technologies' Kickstarter campaign ended on April 16, 2025, reaching ~$108,000 in pledges. The book and associated kits can now be ordered from EIM directly, with details below. EIM used ...

Digital-to-analog converters produce an analog output which is proportional to a digital input. They perform the opposite function to that of analog-to-digital converters. Digital-to-analog converters ...
