Consider an object that has homogeneously textured surface with maximum spatial frequency of (fx,fy)=(3,4) cycle/ meter and that is moving at a constant speed of (Vx,Vy)=(1,1) meter/second.
Find the sketch the convolution of the given pairs of functions. You can use either the integration or the graphical method for convolution. x(t) = 2e-3t sin(2t) u(t) h(t) = u(t) + 4d(t-2) find y(t) = x(t) * h(t)
The charges q and -q are uniformly distributed over two concentric spherical shells of radius α and b, respectively (a b.
