ISM Bands Around the World

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 Read Article

Choosing the Right Microphone for Embedded Applications

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 Read Article

Which Types of Opto-Isolators Are Right For Your Signal?

Which Types of Opto-Isolators Are Right For Your Signal? An opto-isolator is an electronic device that can be used to pass information between a diode without passing an electrical current. Because there is no need ot directly pass voltage or current between the inputs and outputs in an opto-isolator, these components can be used to provide electrical isolation two regions in a PCB. Opto-isolators act as a protection mechanism, ensuring that harmful electrical currents cannot flow across the device. In Read Article
