Abstract
The measurement units of “decibels” are in widespread use in electrical engineering; both physicists and engineers are expected to use them proficiently. They constitute a logarithmic measure useful for gain factors, attenuation factors, etc. The advantage of using a logarithmic measure is that in a transmission chain, there are many elements concatenated, and each has its own gain or attenuation. To obtain the total, addition of decibel values is much more convenient than multiplication of the individual factors.
