at 16:15 when you give the answer to the integral, should it not be 2(e^(-t) +t -1) instead? exponent of e would be -t as opposed to -tau edit: I see this small slip has been addressed a few times already. Excellent video over all that I'm grateful to have for free.
@glaurung78 Жыл бұрын
the "slip" is not so "small". The whole time, he is supposedly trying to find y(t), the output of the system as a function of time. Then he gives an answer containing τ and t. This is not a calculation error, which can happen sometimes -- it does not even make sense.

So man, First question, I wonder can we do convolution to more than two functions? Second, I have a project, for now, I want to put a chirp inside of a song and detect this chirp in the song in the matlab. Should I use anything involved with convolution? Or should I use Fourier format? Please let me know!
@yarenkaya7872 Жыл бұрын
For your first question, convolution has an associativity property; therefore, you can convolve the functions in the order you want.

What? He confused the shit out of me when he's explaining how to find the convolution of h(t)=2e^-2x and the x(t) he came up with. When t is less than zero, h(t) will go to infinity, not zero, how can the convolution give zero for values of t less than zero?
@LyCaNid6 жыл бұрын
It is the product of h(tau) and x(tau) that is zero. Not h(tau) itself. I see why it might be confusing, but I also think he forgot to mention that for those inputs he uses all function values for tau < 0 are 0. They are causal inputs. So h(tau) follows: 2*e^-tau tau >= 0 0 tau < 0
@zacfubar16 жыл бұрын
Lycanid is correct. We should have explicitly used multiplication by the unit step function in the descriptions of x(t) and h(t), which would make both functions 0 for t

We wanted to show the process more than the result. A graph of the output may be nice, but in this example I believe it would not show any intuitive representation of the convolution process. Also, the graph is a bit difficult to draw accurately as it is not a standard function. For these reasons, we thought it best to not graph the output. - Andrew

Were sorry for your confusion, the use of tau here is only a dummy variable. As you can see in the definition of convolution, the tau is integrated out. The tau is simply used to represent the function variable as we slide the "input" in time. I hope this helps! -Andrew

We apologize for this small error. The variable in question should obviously be a ``t'' not a ``tau''. We do these videos in as few takes as possible so that continuity is preserved. Zac is a wonderfully smart man and even the best of us make mistakes. We believe that his explanation of the Convolution theory and worked example is superb, useful, and far outshines the small error in notation. ~Andrew
