Use a phasor diagram to obtain expressions for the in-phase and quadrature components, vi(t) and vq(t), and envelope and phase, A(t) and phi (t), for this signal. Let v1(t) = u(t) and v2(t) = 0. Find the lowpass equivalent signal v lp (t). The bandpass signal in Part (b), x bp (t) = u(t) cos omega c t, is applied to a filter with the following transfer function: Hbf (f) = 1 / 1 + j2 (f - fc) / B for > 0. Use lowpass time-domain analysis to find and sketch the output signal of the filter y bp (t).
