Let the bandpass signal h(t) be represented in the form h(t) = h, (t) cos(27 ft)-h(t) sin(2 ft) Correspondingly, we define the complex impulse response h(t)= h, (t) + jho(t), where h,(t) and h(t) represent the in-phase and the quadrature components, respectively. Hence we may represent_h(t)=Re[h(t) exp(j27)]. Let the complex frequency response of (t) be ()= ()+ j(). Please show that A,(S) == - [ A(S) + *(-D)] . 1 R(0)= - [A(0)-A (-D] () 2j
