A 50-cm length of coaxial cable has an inner radius of 1 mm and an outer radius of 4 mm. The space between conductors is assumed to be filled with air.
The total charge on the inner conductor is 30 nC. Calculate the charge density on each conductor, and the E and D fields.
Let x[n] be a finite sequence that is nonzero for n [N1, N2], and h(n) be a finite sequence that is nonzero n [N3, N4]. Answer the followings: a. For fixed n, what is the range of k that makes h(n-k) nonzero
