    Watching calmly at 80% volume as the z transform just flows inside my mind....plus your voice feels so relaxing....You helped me a lot in coping my difficulties in signals.
    Thanks team Neso

    • @4leafclover202
      @4leafclover202 2 роки тому +8

      He removes u(n) when he changes the summation from -inf to 0 Because u(n) is a unit step function, meaning x(n) = 1 for n>=0 and 0 for n less than zero. So, we don’t care about the values before n=0, because they will be 0.

    • @vavilapallisatyavenkatasan6563
      @vavilapallisatyavenkatasan6563 5 років тому +1

      What i presume is, CTFT is a limited case of Laplace transform, and DTFT is a limited case of Z transform. And by defining ROC for Laplace transform and Z transform, we are defining for a general case than a limited case.
      And if you observe the mathematical expressions of LT, you have "s" as independent variable by which we can relate its existence with s- plane and similarly in ZT, "z" as independent variable by which we can relate its existence to z plane, which is not the case with CTFT and DTFT.

    • @RahulSharma-oc2qd
      @RahulSharma-oc2qd 2 роки тому

      It is a unit step function and unit step function brings this property with itself. It has a step at zero and rises till one at y axis and then stays the same till infinity.
