Abstract: An ensemble of van der Pol oscillators coupled in a ring has been numerically simulated. Peculiarities of chaotic dynamics have been studied by analysis of Fourier spectra and Lyapunov exponents. It is established that chaotic dynamics appearing upon the breakup of multifrequency tori is characterized by a broadband spectrum.

Keywords: ensemble of interacting oscillators, chaotic oscillations, Lyapunov exponents, broadband.
