Consider a continuous-time ideallowpass filterS whose frequency response is H(jw) = { 1, 0, lwl :s: 100 lwl > 100 When the input to this filter is a signal x(t) with fundamental period T = 1r/6 and Fourier series coefficients ak. it is found that s x(t) ~ y(t) = x(t). For what values of k is it guaranteed that ak = 0?
