Suppose that, when sampled at a rate of N = 8, a particular signal is given as: f = 3e0 − 2e1 + e4 − 7e7. What would the signal look like, in terms of the standard basis, if sampled at a frequency of N = 4?

it takes about 30 days for it to break down

iron would move it is magnetic there is a mag field around the current in the wire

wavelength divides in half and speed stays the same.
