    Question on sampling frequency/low pass filter

    Hi all, I have a question relating to sample rates and data filtering. I have a (relatively) high sampling rate of 100Hz, there is some high frequency "noise" present that acts over the range of 1-15Hz. My question is, given that I am interested in much lower frequencies (slow movement...

    Proof that the E.M Field is invariant under guage transformation.

    To prove: F \overline{} \mu\nu = \nabla \overline{} \muA \overline{} \nu - \nabla \overline{} \nuA \overline{} \mu is invariant under the gauge transformation: A \overline{} \mu \rightarrow A \overline{} \mu + \nabla \overline{} \mu\LambdaI end up with: F \overline{} \mu\nu = F \overline{}...

    Unambiguous Evidence for Weak Neutral Currents

    Thanks for that, I was a bit uneasy to see charge violation. Does weak violate anything to do with charge? I remember seeing something about charge violation that only the weak does not strong or e.m Regards,

    Unambiguous Evidence for Weak Neutral Currents

    Homework Statement What observation of the process: (anti muon neutrino) + (electron) -> (anti muon neutrino) + (electron) constitutes unambiguous evidence for weak neutral currents, whereas the observation of (anti electron neutrino) + (electron) -> (anti electron neutrino) +...

    C-R of Laurent Series

    Hi, I mean summing within the contour. 2 \pi x \sum residues = Integral around the contour. You can also use the Laurent Expansion and finding the first principle coefficient. I am unsure what method you would use when presented with a complex integration, Regards,

    C-R of Laurent Series

    When doing complex contour integration one can use the C-R formula or the Laurent series and find the first coefficient of the principle part. What are the selection criteria for choosing these methods? Regards, Hob
