2. Consider the space V = Span(o(t -n) }nez), where 1/4 $ (t ) = IN et Is {o(t - n) }nez a Riesz basis for V and if so, what are the constants A, B? (You should be able to compute these to a high degree of accuracy.) You might find the following fact useful in your analysis: OO 1/4 $ (jn) = e-jsit dt = (27) 1/4e-$2/4
