WebA modified sine wave can be transformed to a pure sine wave by a simple LC filter. The only "problem" is the large inductor, e.g. 1 H for a 300 Ω load at 50 Hz. The capacitor should be 10 μF which is large as well, but not as heavy as the coil. I did some simple simulation here.

Intermediate values of t give nice smooth functions that do indeed look like "sheared sinusoids". (When t = 0 exactly, taking the formula literally gives you 0/0.

WebMar 11, 2024 · The movement of a sine wave to the right a distance d may be accounted for by replacing x in the above formula by \(x - d\). If this movement occurs in time \(t\), then the wave moves at velocity \(c = d∕t\). Solving this for d and substituting yields a formula for the displacement of a sine wave as a function of both distance \(x\) and time ...
