Editor's Note: We have strived to maintain accessibility in our Bring Science Home activities by limiting the required technology. We recognize technology is now more widely available than it was when ...
In Decibels: Use with caution, I reviewed the concept of decibels as a ratio of two powers (and sometimes voltages). Decibels are also used to indicate absolute power and voltage levels by specifying ...
Decibels (dB) are a unit for measuring sound. Since sound reproduction is critical for the home theater experience, it's ...
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 ...
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 ...
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 ...
