As described above, except in step 4: twist with twice the rate while crossing the graph, twisting 720 degrees for one period. - Note that you will need twice as many sliders (red and blue), and that it may be difficult to position the sliders correctly.

Use two Helix constructions, joined at the axes. Then proceed as described above, except in step 4: twist a full 720 degrees for one period. While doing so you will need to shift the Helix half a slide-distance towards the left after adding - each slider.

- In step 6, use variable weights instead of blue sliders to more simply determine the amplitude and phase for each half of the period (separate measurements), - and then combine the resulting weights for finding the resulting amplitude and phase. The latter alternative is useful if you just want to - know the amplitude and phase, without the need for synthesis.

Construct a more flexible Helix, where all the rods can be turned freely around the axis. For determining the second harmonic, simply evenly arrange all the rods so that it turns a full 720 degrees over the axis. With this construction it is desired to have a large number of rods, for accuracy. The advantage of this construction is that it is a more general construction, and can even be @@ -177,18 +192,23 @@
The current design is not very accurate, especially when needing to determine the higher order harmonics.

A better design would be one that has many freely rotating rods. The recording process would be much easier. Recording would be done in a single pass, with all rods' angles set to 0, creating flat set of rods, like an abacus. - Then for each harmonic to analyse, apply a 360 degree rotation to the rods, evenly spread across the axis, and determine the rest-weight in each case.
