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

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 there are relatively small dynamic microphones, they come with a broad range of options and technologies. They range from relatively simple and popular condenser-type microphones to state-of-the-art sound conversion solutions incorporating
