Signals and Systems Lec -16(a): Problems on LTI Systems
In this lecture, i have solved problems on Properties of LTI systems and finding convolution between two discrete time signals.
i have solved one problem on convolution between two continuous time signals and two problems on discrete time signals. and also i solved few problems on LTI system properties like how to identify stable and causal systems.

in this lecture only sir sry i commented there....
ReplyDeletelast problem of this lecture
x(n)=(-1)^n[u(n)-u(-n-8)] & h(n)=u(n)-u(n-8)
we have found x(n) value limit exist upto -7 to 0.then there is a amplitude scaling factor (-1)^n. it should be multiplied with the x(n).whether im right ah sir.......?but i thnk we have left that scaling factor.....?if im wrong sry ..can u please check..
no don't be sorry, you are making valid points which i forgot to write that scaling..anyway no problem whatever we have done that also is the right answer..i should thank you..you can solve by adding that scaling factor.
ReplyDeleteya i done sir in that i have doubt in which the value have been randomly changes from(-1,1,-1,1...-1,-1) ,-7 to 0..i have took h(k).then how to solve, to find the area ....i dont know to put the limit....can u help me....
ReplyDeleteya we have to shift one of the sequence...you can make constant which is randomly changing one and other sequence ...then when we do summation substitute the (-1)^k..
ReplyDeleteotherwise i will do that and mail you by evening
Deletesir please provide circuit theory different model problems......
ReplyDeleteSir for that same problem (-1)^n can you post the solution sir.
ReplyDeleteSir in problem no c) in finding causal nd stable system. h(n) = (-1/2)^n u(n) + (1.01)^n u(n-1) when finding sumation i am getting value as 100 but in video you said it will be infinity. Can you check that?///
ReplyDeleteY(t) = x(t/3) it is non causal ...is it right sir ??
