Nonlinear transducers

• Explain the fundamental differences between linear and non-linear systems
• Account for the dominant nonlinearities in electrodynamic loudspeakers and to predict how a given nonlinearity will affect the movement of loudspeaker
• Explain how the loudspeaker behaves in the non-linear mode, including harmonic spectrum and DC position
• Compare and apply techniques for modelling physical systems in discrete time
• Carry out measurements and calculation of common measures of distortion
• Account for basic methods for identifying model parameters
• Explain and apply numerical methods for solving nonlinear differential equations
• Explain the fundamentals of non-linear compensation
