We present a 4-dimensional electrical model for realizing a multiplierless hyperchaotic system using two Duffing oscillators with a nonlinear resistive coupling. The corresponding hyperchaotic attractor is not only numerically verified through investigating phase portraits and Lyapunov exponents spectra, but also realized experimentally by a simple electronic circuit.
