Basics of Signal Integrity Analysis
A Guide to Mode Conversion, Its Causes, and Solutions
Differential pairs are most often discussed in terms of their impedance and length matching tolerance, both with the goal of ensuring proper termination at the receiver and suppression of common mode noise. On interconnects, such as board-to-board connections or cascaded transmission line arrangements, you have an important EMC compliance metric that is sometimes overlooked. This is mode conversion, which can be visualized in an S-parameter

Differential Pair Impedance: Using a Calculator to Design Your PCB
Do you know what to look for in your differential pair impedance calculator? We've compiled the important information you need to know in this short guide.
How to Impedance Match and Terminate Capacitive Loads
Impedance matching and capacitive load termination are examined in this article.
Transmission Line Impedance Measurement: Even vs. Odd Mode
If you need an accurate transmission line impedance measurement, here are the important values you need to use in your next board.
How the Gibbs Phenomenon Produces Measurement Artifacts
The Gibbs phenomenon is a measurement artifact that can be mistaken for real signal integrity problems like ground bounce, ringing from reflections, or resonance on short lines.

What is Signal Integrity?
Learn about the basics of signal integrity and how you can ensure your PCB layout complies with best practices for signal integrity.
ISM Bands Around the World
ISM bands (industrial, scientific, and medical) are parts of the RF (radio-frequency) spectrum reserved for general use by, as the name suggests, scientific, medical, and industrial devices. Their creation was in response to specific demands by these industries for access to the RF spectrum to perform functions without having to compete with the traditionally intensive users of RF, the communications, and defense sectors. The critical thing to
Choosing the Right Microphone for Embedded Applications
If you need to capture sound waves for your electrical device to process, you'll need a microphone. However, microphones these days have become very advanced, and there are so many options to choose from. While they are relatively small, they come with a broad range of options and technologies. They range from the relatively simple and popular condenser type microphones to state-of-the-art sound conversion solutions incorporating internal
