Termination resistors and the ratio units of voltage and power — dB — are interrelated topics. The dB units can refer to voltage or power, and conversions between voltage dB units and power dB units ...

Decibels are commonly used in electronic systems that include RF, audio, and more recently, signal integrity. While many engineers already think in decibels, if you mostly work in the time domain, you ...

If you’ve hung around electronics for any length of time, you’ve surely heard of the decibel (often abbreviated dB). The decibel is a measure of a power ratio. Actually, the real measure is a bel, but ...

In the radio-frequency (RF) microwave test and measurement world, engineers often deal with the power measurement unit of dBm instead of wattage (W). However, when entering the audio measurement arena ...

Megan Gerhart, Au.D. received her doctorate of audiology from the University of Florida. She has experience helping pediatrics to geriatrics both in private practice and medical models of care. She ...

We live in a noisy world, from traffic and aircraft congestion to construction sites, TV shows, and many other sources. But understanding dB measurements can help, as we will soon see. Noise is an ...

For those looking to gain a deeper understanding of how audio works, whether to make better-informed decisions or simply for the sake of curiosity, it's useful to lay down some ground rules that ...

From the Richter scale to sound pressure, many modern units utilize the logarithmic “base 10” system. But to many engineers, the decibel (dB) remains one of the trickiest concepts of test and ...
