At first I was like Wow this is not clear, he talks super fast. I don't have that level of English. And now! I got super tired at the weekend and I could clearly hear what he had said and I could understand and relate material to the incoming semester. Awesome! Magnificent! Many thanks. I'm really glad I came across this video again today. Super cool.
Hi. Thanks again for making these videos. At [3:14] there is an error in the expansion of the z-transform of the unit impulse function: 1z^-0 + 0z - 1 + 0z^-3 + ... That should be: 1z^-0 + 0z^-1 + 0z^-2 + 0z^-3 + ... = 1.
Thanks for the great video. Not a criticism but I wish you talked a bit slower . I often watch online lectures at 1.25x speed.. but for yours I felt like I wanted to slow it down! : D. Anyways, good job.
At 2:00 you show a graph and list different values, than you say. You probably switched the sign between -1 and 2, when presenting the time-shifted signal. Maybe you want to correct that, as it is a bit confusing. Thanks for the video anyways!! :)
At 2.12 you show w[n]=x[n-2] but the w sequence you show differs from a shifted x sequence. w is [0,0,3,1,-2,1,0,0] while x is [3,-1,2,1,0,0,0,0]. Why?
That's a mistake on my part w[n] should be [0,0 ,3,-1, 2, 1] w[n] = x[n-2] solving for n = 0 gives w[0]=x[-2] =0 solving for n = 1 gives w[1]=x[-1] =0 solving for n = 2 gives w[2]=x[0] =3 solving for n = 3 gives w[3]=x[1] =1 solving for n = 4 gives w[4]=x[2] = -2 solving for n = 5 gives w[5]=x[3] = 1
