4. The signal m(t) is transformed into m(t) when passed through a quadrature filter (- 90° phase shifter). m(t) h(t) = + m(t) nt (a) If x1 (t) m(t)cosw.t and x2(t) = m(t)sinw.t find the Fourier transforms of x1(t) and x2(t) and express each of them in terms of M(w) where M(w) is the Fourier transform of m(t). (b) (i) If x (t) = x1 (t) + x2(t) and y(t) = x1(t) – x2(t), find X(@) and Y (@) and simplify them. X (w) and Y(w) are the Fourier transforms of x(t) and y(t) respectively.
