Following previous work on computing approximate frequency response functions for the Duffing oscillator under white Gaussian excitation, an approximation is obtained here for the coherence function. A PadeΒ΄approximation of order (1,1) is made for the asymmetric Duffing oscillator (i.e. with non-zer
