• curprev 20:2120:21, 14 November 2024 Em3rgent0rdr talk contribs 71,331 bytes +73 →Derivation: describe in English what this analysis interval is: "over one period of that sinusoid starting at any 𝑥_0". Also I don't know why the degree sign in "90º" has a line under it, but replacing with standard Unicode degree sign "90°". Add spacing in cross-correlation equation between f and (x-tau) so doesn't appear like "f" is a function. undo Tag: Visual edit
