A first-order hold is a sampling system in which the output xfOM(t) (solid curve) is equal to the input x(t) (dotted curve) at every tenT (where n is an integer) and a linear interpolation between the points at all other times. m) when kI 0 otherwise trit) A) ExpressS XFoMt) in terms of: B) Find XFOMio) C) What is the practical problem in implementing this system? D) Repeat part B if the time domain output is shifted to the right by T E) Determine the proper reconstruction filter to retrieve x(t) from XFo(t) as defined in part D
