Methods of frequency range division of the radio spectrum

The radio spectrum consists of all frequencies that have electromagnetic radiation, which spreads energy in the form of waves and propagates through space. Longer wavelengths and lower frequencies make up the radio spectrum. Shorter wavelengths and higher frequencies make up the spectrum. We...

Free Download EMC Industry dB Conversion Formula dBm-dBuV-dBuA Conversion Formula Chart

EMC testing process requires frequent conversion of dBm, dBμV, dBμA and other units of dB conversion formula, linear to logarithmic display conversion by heart is difficult to complete. This article describes how to quickly use the computer for dB conversion method...

EMC Interference Coupling Methods for Integrated Circuit ICs

Integrated circuits (ICs) are often the ultimate source of unintentional electromagnetic radiation from electronic devices and systems. However, ICs are too small to radiate on their own. In order to radiate fields strong enough to cause interference problems, ICs ICs are coupled in a way that EMC interference...
