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 ...
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 ...
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 ...
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 ...
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 ...
