We show that, for highly oscillatory ordinary differential equation problems, the modulated Fourier expansion approach can be advantageously used to understand and analyse the heterogeneous multiscale methods introduced by E, Engquist and their co-workers.
Key Words: modulated Fourier expansions; heterogeneous multiscale methods; highly oscillatory differential equations; inverted pendulum
