Our life is considered as a Modulating signal(base band) which doesn’t have any meaning if we dont lead the better way and reach our destination, and to achieve that and to reach the destination the strength in ourselves is not enough, so you need to a have a friend who acts as carrier to your life helping you to reach the destination safely, which would have been highly impossible without that to reach the destination.
At the same time the carrier(friend)should be in such a way that, they helps us to reach the destination in a proper direction and with good strength(INTERACTION), even if it over crosses or under crosses the boundaries of FCC(friendship) then ultimately results in INTERFERENCE(Misunderstanding).
The amplitude(level of understanding) should be high enough to ensure the proper transfer of signal.
The Noise (Misunderstanding) level should be as low as possible and see that the
Power level(Relationship) maintains at a optimum level.
Another important issue is that you should act like a DUPLEXER (flexibility and compatibility combined) so as to be ready to solve the problems no matter in which and whose way it comes.
Finally I (modulating) + U friends (carrier) = V(Modulated signal)
Let me give the final conclusion,
that you friends are my inspiration
This is my sole hearted declaration.
