Rather than say "trick", instead spell out what the "trick" presumably is for readers that can't connect the dots: a "voltage doubler". Add nbsp and hyperlinks. current Tag: Visual edit

• 02:0802:08, 22 November 2024 diff hist −23 m Lithium iron phosphate battery "Watt" shouldn't be capitalized as a unit. Tag: Visual edit
• 02:0602:06, 22 November 2024 diff hist +230 Watt-hour per kilogram →SI Units: Best to not introduce with "In the SI system of measurement," or to give Wh/kg as the "SI symbol", because the watt-hour isn't a SI unit. Added context about hour not being SI but is accepted for use with, and how the conversion works. Tag: Visual edit

• 20:2120:21, 14 November 2024 diff hist +73 Fourier series →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. Tag: Visual edit

• 19:4719:47, 1 November 2024 diff hist +139 Body capacitance move effects of spark out of intro, cause that is tangential to the topic of body capacitance and intro should just summarize anyway. Tag: Visual edit

• 16:0616:06, 15 October 2024 diff hist −26 Roll-off →First-order roll-off: Give more digits to the 6 dB/octave approximation, so readers see how approximate it is. Deleting vague "within normal engineering required accuracy" because engineering accuracy is a relative term that depends on application and this one-third percent above 6 dB error may or may not be significant. Better to give the 20 dB/decade exact number rather than the approximate 6 dB/octave when have a choice. Tag: Visual edit

• 15:0115:01, 15 October 2024 diff hist +644 Log amplifier →Drawbacks: The Linear Technology citation was not exactly saying this and was talking about BJT-based converters, not the simple diode converter anyway. Moved that source instead to be a new Drawbacks section at the end of the Transdiode configuration and add some more points from that source, whose primary conclusion seems to be the claim that modern delta-sigma with digital calculation is superior. Add temperature proportional to kelvin too. Tag: Visual edit
