Hello guys.
I indeed know what dB is and how it does work.
I of course know two dB formulas for Power and Voltage too.
But most of times I see somebody or a Paper just talk about dB, yet do not refer if they mean dB calculated by VOLTAGE or by POWER. For instance somebody just told me "is using a 40dB filter sufficient for one of my modulator circuits or not". or somewhere I saw that "the gain of an antenna or a booster is 110dB" and so on.
The question which comes out is how to realize If guys or the papers and etc refer to dB voltage or dB power when They talk about dB values??
Is this problem just for mine or you guys have trouble to realize such situations??
Thanks for any input
