Consider the optimum detection of the sinusoidal signal s (t)

Consider the optimum detection of the sinusoidal signal s (t) sin (8pt/T), 0 = t = T, in additive white Gaussian noise.
(a) Determine the correlator output assuming a noiseless input.
(b) Determine the corresponding matched filter output, assuming that the filter includes a delay T to make it causal.
(c) Hence show that these two outputs are the same only at time instant t = T.
