    Why there is minus sign in my tablet phone signal strength?

    Very complete explanation... It's cool, means if I know the signal strength, in ideal condition I can estimate the nearest tower surround me! What an amazing Physics! Thank you very much to davenn and f95toli :D

    Why there is minus sign in my tablet phone signal strength?

    Oh I see, so It means the receiving signal to the receiver is about 8pW... Does it mean when the 8pW becomes higher then the signal is better to receive data/phone?

    Why there is minus sign in my tablet phone signal strength?

    Oh that is receiving signal... Yeah it's quite interesting to have the setting in Samsung Galaxy Tab to know the signal strength in numbers... What do you mean usual "S" meter? N when it signs minus, does it mean the signal power is decreased when coming to the receiver?

    Why there is minus sign in my tablet phone signal strength?

    I have tablet phone samsung galaxy tab... when I check the signal strength, it shows -82 dbm... I thought it is produced by the Signal PA (Power Amplifier) on the PCB... According to what I know, the signal from the handphone is so weak to reach the nearest terrestrial station on the...

    Undergrad Find the value of x by using least means square method

    I can't understand this problem, anyone can help me... Given a function y = 4x2, you are required to find the value of x that will result y = 2 by using the Least Mean Squares method. Use initial estimate x0 = 1 and learning rate η = 0.01. Write down the results of the first 10...

    Linear Algebra Vs Mathematical Modeling -Importance in relation to physics

    Hmm, i try to give any opinion yah... When I study about linear algebra,I found that it really helps me to calculate many calculation in Physics easily without doing too many substitution and elimination etc... For example if u learn 2-4 degree freedom of oscillation, mechanic oscillation with...
