Advanced Digital Signal Processing and Digital Communications a.    Determine the impulse response h (t) Sketch x(t) and h(t) on functions of time The filter is matched with (mf) linear The filter is designed to provide Max signal to move power ratio at its output for a given the transmitted wave form. X(t) t/2    T    ½ t    t Impulse response h(t) = x(t-T) Signal wave form Mirror the signal wave form x(-t) A/2 -t    t -T/2    -A B) Suppose the signal x(t) is applied to the match filter h(t). Graphically  determine and filter the filter output v(t) as function of time. The y(t) =h(t) × x(t) A/2    X(T-t)= h(t) -A    t/2    T c.    PSD= No/2 Energy beyond Eb of s(t) and s(-t) Since the signals are antipodal S1(t) = - s2(t)1the epitome threshold value is 0 i.e y0=0. The correlater receiver is Average energy Input signed is changed to X(t) =      A              0
