Lord Kelvin's harmonic synthesizer is basically Henrici's harmonic analyzer in reverse. Originally designed as a tide predictor in 1876, the system can combine numerous component waves—in some devices, up to 64 separate components—into a single end result. This was used by Dayton Miller to check the results produced by Henrici's analyzer against the original phonodeik curve. The version used by the Case physics department consists of 32 wheels controlling the motion of a single cable that traces out the final amplitude with a stylus and sliding draft table.
