    What happens when you have an input where the zero is somewhere in the middle along with the impulse zero somewhere in the middle? How do you find the zero of the y[n] in this case?

  • @TheVideoVolcano
    @TheVideoVolcano 6 років тому +2

    why do you consider the impulse response n=0 as the 2nd digit in the sequence?? It makes sense for the x[n] because its the first digit.

    What if you move the origin for the signal x[n]? like if the function is x[n]=[4,1,2,-5]. The origin is now at 2. How would you convolve these two?

    @illegalallan9256 9 років тому +7

    I completely understand why your 4 at your input signal is n = 0, but i dont understand at your impulse responds that 2 is your n = 0, why isn't it 1?

      @spongebob1477 7 років тому

      maybe it's just an example he design to be 2 at n=0
      it's also mathematically ok to make it 1 at n=0, but will lead to different answer
