I think the following statement, "E-field (and the H field) are always perpendicular to the direction of propagation of the EM wave", means that the instantaneous directions of E and H would be orthogonal to the direction of wave propagation. So may be you need to think in terms of the classical...
Hi, sorry for not being clear enough. eeg readings have been taken from 45 different electrode positions on the scalp @ 256 samples/sec. These signals usually do not have components greater than 128 Hz. I intend to calculate time correlation coefficient between each pair of signal (there are...
Hello,
I need to calculate the correlation betweeen a pair of eeg signals in various bands (delta, theta, alpha...). Before I do so, I am filtering out frequencies below 0.5 Hz. (and also notching out 50 Hz.) I wonder whether the phase changes introduced by these filtering operations would...
How did you prove it for the supremum case? If you can prove it for the supremum, this proof here is self-contained because the given metric is always less than the supremum.
