12 - Understanding Signal Strength in mW and dBm

[@parama_01]

Finally, I can understand this! Thanks in advance!

Great lecture, thank you!

Thanks so much for clarifying this. I install tv antennas with my dad and we use a signal strength meter to help dial in the direction we need to point the antenna to get the best signal. I've wondered for a while why the DBm is always a negative value and now it makes sense

Its helps me a lot, thank you

Sir, you are so amazing, you can teach this 100x better than my professor for this course.

[@TheHugguan]

thanks for the explanation. now i know -60dbm is actually 0.000001mW

Nice video.. awesome

Awesome!!

[@firashatem658]

Thanks alot for this explination

[@pbaemedan]

Good information, but you sould introduce 10 x log(watts).

Great video, thanks

What is common channel signalling?

Tell me about Signal

evening GT -so its 1mW x 10 [because 10 dB is 10x the power]
so for 13dBm you are then referring to the previous answer of 10mW to get the doubling of 10mW [because of the 3dB = 2x] dB in 13 ?] to make 20 mW ?
in other words it's not 3 [2X Power] dB X 1 mW but 2x the 10mW of the previous answer?
I hope this makes sense -I think that's what I'm asking but not put very well !
Cheers these are good presentations

English please
