There are some things in the world of electronics that are just confusing to people, though they are actually simple underneath. The decibel is one of them.
If you’re into electronics you probably have heard the term decibel or dB thrown around.
Even if you’re not an electronics enthusiast at all, you may have heard the term used in situations dealing with sound.
Understanding the decibel (or dB) is important for any aspiring electronics geek.
Decibels show up in amplifier design, filter design, Bode plots, antenna specs and more.
Fortunately, the concept of the decibel is relatively simple once you understand it. In fact, this post will probably be shorter than most of the others due to the simplistic nature of this unit.
