Answer Posted / 10dell
db is relative scale
3db down scale implies that Pout/Pin = half
means output power is half
and below this half power the output is no loger useful,and only the output above 3db scale is cosidered
so we take the range which is defined by 3db line as bandwidth
according to this we can define bandwidth as the range of acceptabe output
