We present the classical analogy of Fano interferences in helpful view to understand Fano behavior of phonons excitation as the interaction of two harmonic oscillators in damped oscillation system. In order to obtain more informative explanation, we demonstrate the coupled oscillator motions in javascript using numerical integration method of 4th Order Runga Kutta. A detailed discussion of Fano spectral distribution is shown by considering some varied oscillation parameters including natural oscillation frequency, damping factor, coupling constant, as well as applied external force. It is further shown that the oscillation phase-shift differs in those varied oscillation parameters. The range of allowed values of parameters to get the appropriate results will be listed in this article. © 2019 Published under licence by IOP Publishing Ltd.
