If you don't provide correct answer how can we verify our answers??

1. Time variant sys. y[n]=x[-n] Because if we do time shifting by -k in input side then output will be y'[n]=x[-n-k] But if we do time shifting by -k in output side then output will be y[n-k]=x[-(n-k)]=x[-n+k] And x[-n-k] is not equal to x[-n+k] 2. TIV system 3. TV system (time scaling) 4. TV system (time dependant coefficient)

[@Raviteja-zu5sy]

how second one is TIV

[@jishasujith9772]

Second question also time variant, since there is a time scaling

sir plz a complete video on Microprocessor

[@jayrolopez8277]

What if the expression already has a time shift? for example, x|(2m-3)|. Is this T.V. because it has the 2m ( Time scaling)?

[@awesomearchit111]

Sir is the following system linear or non linear y(t).dy/dt + 3y(t)=x(t)

[@paramitasadhu5885]

in your lectures u hv concluded that linearity is independent of amp scaling . so how this system is being Non.Linear?

[@parththobhani9248]

i think, It is non linear because of y(t)dy(t)/dt , as per superposition if we separately add it gives y1(t)dy1(t)/dt+y2(t)dy2(t)/dt ,but if we combine y1(t)+y2(t) dy1(t)+y2(t)/dt it gives 4 terms so it is nonlinear term

[@makingmycareer2608]

All except 2 are TV

[@raviprakashmeghwanshi5802]

brother, I think this is an additivity case that you have written.

[@makingmycareer2608]

@@raviprakashmeghwanshi5802 Yaa, sorry!! Got confused between linearity and Time Variance. It is time invariant.

[@ujjawal1366]

Only 2 is TIV others are TV

[@kimosaid3221]

Ok

[@rishabhbahoria1298]

1) TIV because it is a special case of time scaling which is time reversal remaining 3 are TV ..... sir plz correct me if i am wrong because HW problem page of SS is not accessible !!

2 , 4 tiv

[@vivekiyer9482]

@@vaibhav_pal.vp. I think 4th is TV Because last term will be cosn×x(n) that means second condition not be satisfied That is coff is not constant that is cos(n) is variable hence time is variant.
