Abstract:
In this paper, a first-order generalized memristor and a polynomial memristor are designed to construct a dual memristive Wien-bridge chaotic system. The proposed system possesses rich dynamic characteristics, including alternating between the periodic state and the chaotic state, variable amplitude and frequency, coexisting attractors, and a locally sustained chaotic state. The dynamic behaviors are obtained and investigated by using Lyapunov exponents, bifurcation diagrams, phase portraits, time-domain waveforms, frequency spectra, and so on. The presented chaotic system is implemented by using a digital signal processing platform. Finally, the National Institute of Standards and Technology test is conducted in this paper. Since the system has rich dynamic behaviors, it has great potential value in encryption engineering fields.

RLC Circuit as a Damped Oscillator
Consider a series RLC circuit. Here, the presence of resistance in the circuit leads to energy loss due to joule heating in the resistance. Therefore, the total electromagnetic energy in the circuit is no longer constant and decreases with time. Since the magnitude of charge, current, and potential difference continuously decreases, their oscillations are said to be damped. This is...
