Quick question

Answer 1

How to do find the amount of measurements needed to improve the S/N ratio to another S/N

Answer 2

what is S/N ?

Answer 3

sound to noise ratio

Answer 4

I remember hearing it is proportional to \[\sqrt{n}\] I think

Answer 5

by measurement are you going to sample like one point on the signal at a time

Answer 6

I was given data points, ten exact, for two instruments. I was told to find the S/N ratios for both an compare. I was supposed to determine which instrument was worth keeping. Last question was to many measurements are required to improve the S/N ratio of the data obtained on one machine to S/N ratio that is obtained on the other.

Answer 7

here I have a chart I'll screen shot it so you can see.

Answer 8

okay sure

Answer 9

10 replicate measurements using
a known standard of Ibuprofen that has a concentration of 4.70 (uM)

Answer 10

okay i see now

Answer 11

so without the noise, it should be a constant output right

Answer 12

yes.

Answer 13

the S/N for the TR-50 is ~7.18 and the S/N for the TR-100 is ~33.64

Answer 14

so you got htose values by taking the standard deviation im assuming?

Answer 15

\[\frac{S}{N}=\frac{average}{Standard Dev}\]

Answer 16

okay gotcha

Answer 17

I'm supposed to this and I cant remember how
How many measurements are required to improve the S/N ratio of the data obtained on the TR-50 to S/N ratio that is obtained on the TR-100?

Answer 18

ohhh okeyyy i see

Answer 19

the question before looked kinda confusing

Answer 20

I'm not great at explaining =/

Answer 21

okay so, for me id completely math this so it would take a while im not too sure about all the formulas that are given for statistics

Answer 22

but you have a STD for a sample number of points, so you have to find the true standard deviation of the less accurate one

Answer 23

let me outline everything that needs to be done before actually seeing how to math it

Answer 24

alright sounds great
