Will please explain what is real(x[n])

The best lectures that i found on youtube on signal and sytems . Thank you so much sir.

[@iEntertainmentFunShorts]

Really i can't say in words.I m in 3rd year CS students.In 2nd year i had watched your complete series on Digital its awesome sir.Till now i solved almost all cs digital problems on gate.its just because of you sir really thanks a lot and huge respect for you SIR.

Can you explain probability and theory stochastic process (PTSP?)

[@rishabhbahoria1298]

1) Not sure BUT it should be linear because the input is given as "Sa[n] 2) Linear 3) NonLinear 4) Linear

Sir a system is such that it convolutes the discrete time signal with itself I.e. output is X[n]*X[n] ...is the system linear or non linear. Thanks.

[@vavilapallisatyavenkatasan6563]

When you say convolution, obviously the system is a Linear Time Invariant(LTI) sytem. For any given LTI system, to find its response you use convolution.

Why the sound is very low

[@palletinavanthreddy2826]

Can u explain how x{sa(n)} is linear

[@pratyushkesharwani2179]

because time scaling of sa function is occur inside x[n]. if sa is present outside i.e sa(x[n]) then this will be non linear

Any operations on t has no effect

[@joshuaaa3337]

what about division y(n) = 1/x(n). will the system be linear?

[@hanu5090]

Non linear It fails loa &loh

[@RahulSharma-eg7jy]

Non lineae because of x inverse [n]

[@rohitdatwani8467]

Sir why is number 4 linear?

[@reshmipriya3358]

Summation is linear operator

[@Zappango]

@@reshmipriya3358 but summation plus shifting is a linear....Here we don't have shifting

[@youngdumbBroke21]

how first question is linear? sa function is non-linear duh

[@ohgorunney13]

Can someone explain to me? y[n] = x[n]x[n-2] Is it linear or non linear?

[@Sandeep-tx5jh]

It's linear

[@reshmipriya3358]

Linear....

[@kidvschild7240]

Non linear

[@AyushMo]

well shouldn't it be non-linear? For 0 input, linear systems produce 0 output y[0] = x[0] . x[-2]

[@terribleloser.24]

Its non linear... It do not support law of additivity there are two extra terms when you compare the two equations

[@neetapandey1474]

Can someone explain 1 and 4 homework problems

[@akibjawed5076]

HW1 : "sa" operator is operating on an independent variable not on system input which is a case of time scaling, therefore, it is a linear system. HW4 : summation is corresponding to integral operator of CT-System, hence summation operator is linear, therefore, the system is linear

[@ujjawal1366]

Only 3 question is non linear.

[@dipubansal2768]

sampling function is a non linear function but in 3rd ques you solved it as a coeff. and termed it as a linear function.

[@reshmipriya3358]

Its non linear function of t....focus on 'x'

[@kavinaya.k2573]

All are linear system

[@vivekiyer9482]

3rd is Non Linear I guess Because of its real according to conclusion.
