Abstract
An oscillator for generating non-sinusoidal, preferably triangular movements from a harmonic synthesis of individual sine oscillations. The oscillator comprises a plurality of mechanically intercalated resilient oscillator systems which each comprise an exciter drive means drivingly coupled to an oscillatable element. Each oscillator system has a natural frequency chosen in accordance with Fourier analysis of the oscillatory motion to be synthesized. From the total of the natural frequencies the desired motion is generated.
