| Mar 27, 2012 at 23:35 | comment | added | stackoverflowuser2010 | I appreciate the help, but as I said, the data that I'm reading (e.g. from microphone, accelerometer) doesn't look like an exponentially decaying signal, or at least it doesn't look like it. | |
| Mar 27, 2012 at 22:57 | comment | added | stackoverflowuser2010 | Yes, I know the convergence of a geometric series sum. However, I don't see why that is useful here. Why would the values of $x(n)$ take the form of 1, $x$, $x^2$, $x^3$, ...? The signals that I'm reading (microphone, accelerometer, etc.) certainly don't have values like that. | |
| Mar 27, 2012 at 18:01 | comment | added | stackoverflowuser2010 | What do you mean by "the actual value is always obtained by mathematical manipulations rather than by explicit computation by adding terms"? How can you get a final actual value unless you do perform the summation? | |
