We have studied the dynamics of two bilaterally-coupled non-oscillatory Rayleigh–Duffing oscillators (RDOs). With the increase of coupling factor (CF) between RDOs, birth of periodic oscillations observed. For increased values of CF, dynamics becom

Dynamical responses of third order phase locked loops with resonant filters are examined by modifying the control signal applied to loop oscillator. Using signals obtained at some internal nodes of loop resonant filter, the control signal is modified

Nonlinear dynamics of optical phase locked loop (OPLL) in presence of loop delay, considering proportional plus integrating type loop filter (LF) has been studied. Analytical and numerical results show that with proper choice of frequency gain, chaos

Nonlinear dynamics of optical Costas loop (OCL) has been studied in the presence of loop delay. Analytical predictions show that, when loop delay exceeds some critical value, the loop fials to lock to the input optical signal. For large value of loop

The response of an X-band angle modulated communication system is studied where two different chaotic signals have been mapped to represent 0 and 1 bits of information bearing data stream and is used as modulating signal. A bias modulated Gunn oscill

The effects of periodic perturbation on a solid state microwave (SSMW) Gunn oscillator (GO) has been investigated in two different ways of application of the perturbing signal (PS). In the first method, named as additive perturbation (AP), the PS is

The dynamics of an optical phase locked loop (OPLL) with first order loop filter having inherent loop time delay is investigated. In the presence of delay, the system is modeled as a third order autonomous system. In the out of lock condition or duri

The consequences of unequal propagation delay of the sampled control signals along the two arms of a class of digital tan-lock loops (DTLs) have been studied in this paper. The said delay is considered as a fraction of the basic sampling period and i

In this paper, we have examined effects of forcing a periodic Colpitts oscillator with periodic and chaotic signals for different values of coupling factors. The forcing signal is generated in a master bias-tuned Colpitts oscillator having identical
