Chaotic Dynamics of a Third Order PLL with Resonant Low Pass Filter in Face of CW and FM Input Signals
نویسندگان
چکیده
Nonlinear dynamics of a third order phase locked loop (PLL) using a resonant low pass filter in the face of continuous wave (CW) and frequency modulated (FM) input signals is examined. The role of design parameters of the loop resonant filter and the modulation index of the input FM signal on the system dynamics is studied numerically as well as experimentally. The occurrence of chaotic oscillations in the PLL is verified by evaluating some well-known chaos quantifiers like Lyapunov Exponents from the numerical time series data.

متن کاملSecure Communication using Chaotic Synchronization of PLL
A technique of secure communication via chaotic synchronization is proposed. A suitable frequency modulated (FM) signal is used to drive two different phase locked loops (PLLs) in chaotic region to obtain two different chaotic signals. Out of these two signals one will be transmitted to the receiver PLL depending on the digital data. Receiver PLL synchronized with the transmitted chaotic signal...

In this paper we describe a generic receiver as a single channel S-band receiver and it is composed of two modules. The first module (down converter) consists of an input band pass filter, LNA, image rejection filter and down-converter with a PLL local oscillator. The second module consists of the IF module derived from the VHF receiver. The IF module consists of a low pass filter, 20MHz band p...
