A three-switch function module constructed by symbolic function is proposed. By detecting the reference voltage, the system can change the connected memristor or connection mode. The improved nuclear magnetic resonance (NMR) laser system with this module obtains more excellent dynamical characteristics, and with the change of parameters, there are many types of attractors coexisting phenomenon. The dynamical phenomena of the system are analyzed by using bifurcation diagrams, Lyapunov exponential spectrum, complexity spectrum, etc. An analog circuit corresponding to the improved NMR laser chaotic system is designed, and the system is implemented on the DSP platform. The rich dynamical characteristics of the improved NMR laser chaotic system provide a basis for its future applications.
