The total vibration, which is the sum of the two vibrations above is as follows: X = X 1 + X 2 = asin(ω 1 t) + bsin (ω 2 t) (3) Any vibration can be shown as a series of sine functions with the circular frequencies (i.e., ω1, ω2) are referred to as the harmonics of the primary frequency ω. The equation is also known as a Fourier Series.
