Chapter 3Introduction to Biochemical Oscillators and Complex, Nonlinear Biochemical Systems

First, note that many nonlinear systems are not complex; however, many complex systems are nonlinear. The Ÿrst and most salient feature of a nonlinear system (NLS) is that it does not obey superposition, and thus cannot be fully characterized by its impulse responses, or by convolution, linear state-variable algebra, or transfer functions.
