Great video. I am starting my UT training and got to the section on DB, you really helped me learn the basics but cant seem to get my head around the problems where you need to use anti log.
Try to think of it this way when logs are used in the exponent - say you raise a base 10 to “log x/350” ... I see it as ... what number must I raise 10 (we assume the base in that exponent to be 10) to to arrive at x/350? After you apply that rationale you arrive at x/350 as the logical final value. Hopefully that helps. A formal proof on it would make my brains explode for sure

This is a very practical and informative video. The books that I have read were vague on how to apply the formula. Thank you for breaking it down.
Thank you
Great Video! Thanks for your time preparing this video!

It is mostly useless for field work. Thanks for your kind words

Great
Thanks
second practice i am following the same steps but finally i am getting 0.946 ... where i am doing the mistake could you please clear me
That is decimal needs to be converted into percentages. Move decimal to the right two spaces
1) -12
A1 20% ad+32 A2 height? sir please this calculation
796,21%
1. -12dB
2. 240%
3. 4.01%
4. 2551%
5. 44.9%
Perfect!
I tried out the problems, still unsure how to get answer. My answer came ip a few numbers short.Is there another video showing how you solved it?
question # 2 = 237% , how did he gets 240%
It is approximate. Usually the tolerance is + or - 5%
A few numbers short is not a big deal.
This question answers are ....
12
100%
2.51%
2511%
45%
Sir please reply me and I hope your others videos ....
the 800% -25dB was A2=44.9% for me 😆
@@osher87 I do not understand
@@osher87 question number of me 😀😀
@@Dipan....9 last one, you wrote 45%, i got 44.9% in my calculations
1) 12
2) 237
3) 4.02
4) 2512
5) 44.9
For 2nd if u do directly it comes 240
Same for 4th 2880
As they r multiple of 6
Helo sir
