Question: If we substitute the equation x_l (t)= u_c (t)+j u_s (t) in equation x (t) + j ? (t) = xl(t) ej2?Fct and equate real and imaginary parts on side, then what are the relations that we obtain?

Options

A : x(t)=u_c (t) ,cos?2? ,F_c ,t+u_s (t) ,sin?2? ,F_c ,t; ?(t)=u_s (t) ,cos?2? ,F_c ,t-u_c ,(t) ,sin?2? ,F_c ,t

B : x(t)=u_c (t) ,cos?2? ,F_c ,t-u_s (t) ,sin?2? ,F_c ,t; ?(t)=u_s (t) ,cos?2? ,F_c t+u_c (t) ,sin?2? ,F_c ,t

C : x(t)=u_c (t) ,cos?2? ,F_c t+u_s (t) ,sin?2? ,F_c ,t; ?(t)=u_s (t) ,cos?2? ,F_c t+u_c (t) ,sin?2? ,F_c ,t

D : x(t)=u_c (t) ,cos?2? ,F_c ,t-u_s (t) ,sin?2? ,F_c ,t; ?(t)=u_s (t) ,cos?2? ,F_c ,t-u_c (t) ,sin?2? ,F_c ,t
