Answer Posted / vasanthkumar.kvv
at 3dB cutoff frequency is the frequency either above or
below which the out power will become double 0r half of the
original Transmitted or received power .
eg: 50dBm =100W
3dB down is 47dBm = 50W
3dB above is 53dBm =200W
for this double 0r half power variation will start from 3dB
cutoff onwards so we will consider 3dB cutoff.
