The title says it all. I’ve just begun studying CCNA and everything I thought I knew about decibels (the prior musician side of me obviously correlated it with sound) was thrown out the window when I learned that it was also used to measure electrical signals. I’ve been trying to read wikis but none of them really hit on how it can measure both sound and voltage, which are two completely different things…
In: Technology
From my understanding it’s because decibels really just measure amplitude of a signal and are dimension less. So the amplitude of a sound signal or an electrical signal can both be measured in decibels
