How to do Fourier transform for a differential equation?
The Fourier transform is a useful tool for solving many differential equations. As an example, consider a damped harmonic oscillator subjected to an additional driving force f(t). This force has an arbitrary time dependence, and is not necessarily harmonic. The equation of motion is d2xdt2+2?dxdt+?20x(t)=f(t)m.What is the formula of DFT equation?
The DFT formula for X k X_k Xk? is simply that X k = x ? v k , X_k = x \\cdot v_k, Xk?=x?vk?, where x x x is the vector ( x 0 , x 1 , … , x N ? 1 ) .
