BANDWIDTH-- >> in general is the total range of frequencies that a system can handle..
BW= Fmax-Fmin

now.. a system is called open loop when there is no feedback.. when feedback(-ve) is introduced(negative feed used as +ve feed will make the system unstable usually), the gain will reduce .. along with that, it lets the system handle more range of frequencies.. thus bandwith increases.. the principle of GAIN*BANDWIDTH is always kept constant.. thus when gain is reduced, BW increases..

thus closed loop system BW increases compared to open loop..
