See the people below u to realize how lucky you are, whenever you feel that u are unable to do something
1) is there any difference between FM and PM signals.
2)draw the waveform of both.
3)comment on bandwidth of both. Which one is more immune to noise. and why
4)a signal was given and asked to comment on causality and linearity.
5)a sinusoidal triangular signal was given and asked to find the Fourier transform.
6)the ask how can you find the Fourier transform intuitively.
1)tell me about yourself.
2) what is root locus.
3)gave a transfer function which was unstable and asked to comment on stability. Then asked how can you remove the unstability using controller. And realize the system.
4)final value theorem.
5)for a AX=0 how can you find nontrivial solution.
We all know magic. We can do whatever we want. The only requirement is that we have to think about that.
Whatever we think, that will be going to happen in near future.
So if you think positively then only positive things will happen. And everybody wants positive result so think positive. Simple
