Never mind. The Noise power is the variance (S.D. ^2), and the SNR is the Signal Power/Noise Power. Signal Power is A^2/2. PE = 0.5erfc(V/2*variance*sqrt(2)) Thanks anyways.

Yea I have come across many formulas like this, however the problem is I have values for only the time, and volts.

Ah ok, thank you. Is this the method for volt and time values obtained from scope? Currently I have the data in excel. I will read into noise figure. If you have any particular formulas that could give me a start that would be great.

I have values of time, and volts of a noise signal. I am trying to determine the noise power, signal to power ratio and bit error probability. How would I go about doing this? Thanks.

Homework Statement I doing a investigation coursework at the moment for physics A2. I am investigating how the viscosity of oil is affected by the temperature. I am attemping to prove the viscosity decreasing by showing that the damping constant decreases. I have attached a excel workbook...
