RANDOM HARMONIC OSCILLATION
In matters of equipment operation, a random harmonic oscillation x ( T ) =a cos (ω <sub>fix</sub> T+ φ) is often encountered , for which the frequency ω <sub>fix </sub>is fixed and the phase φ does not depend on A, and φ is evenly distributed over the segment [0, 2π], and C is a continuous random variable. Random harmonic oscillation is described in the course « Probability theory mathematical statistics and random processes » in engineering specialties. The very topic of random processes, which includes harmonic oscillation, is not trivial for students. In the literature, the presentation of this material is complicated. This paper presents a summary of the random harmonic oscillation in the course of mathematical analysis and its main characteristics.
