SNRDB= 10*log10(SNR) --> log base 10SNR = 10.^(SNRDB/10)

SNRDB= 10*log10(SNR) --> log base 10

SNR = 10.^(SNRDB/10) ---(1)

SNR = exp(SNRDB*ln(10)/10) ---(2)

How is equation 2 comes as I checked both equation 1 & 2 are equivalent numerically. I am not able to derive equation 2.

10=exp(ln(10))=e^(ln(10)). Put that into one of the 10's in the second equation and use properties of exponents.
 


Thankyou I got it now.Cheers!
 
Thread 'Use greedy vertex coloring algorithm to prove the upper bound of χ'
Hi! I am struggling with the exercise I mentioned under "Homework statement". The exercise is about a specific "greedy vertex coloring algorithm". One definition (which matches what my book uses) can be found here: https://people.cs.uchicago.edu/~laci/HANDOUTS/greedycoloring.pdf Here is also a screenshot of the relevant parts of the linked PDF, i.e. the def. of the algorithm: Sadly I don't have much to show as far as a solution attempt goes, as I am stuck on how to proceed. I thought...
