Answer Posted / cheena jain
An amplitude modulated signal consists of three parts
1.modulating signal
2.lsb
3.usb
the information contained in both the bands is same
so to save power only one band is transmitted
but coz filters are used some information at the edges may
lost due to this a small part of lsb is transmitted (not
the whole)which acts as a guard band.
