Signal Operations If we represent finite-length signals as vectors in Euclidean space, many operations on signals can be encoded as a matrix-vector multiplication. Consider for example a circular shift in C3:delay by one (i.e.a right shift) transforms the signal x = [x0   x1    x2]T  into  x' = [x2   x0   x1]T and it can be described by the matrix         [ 0  0  1 ] D = [ 1  0  0 ]        [ 0  1  0 ] so that x' = Dx Determine the matrix F that implements the one-step-different operator in C3 i,e, the operator that transforms a signal x into 1/√ 2[(x0 + 0.5x1 - x2 )  (x1 - 2x0 + x2 )  (x2 - x1)]T
