Chimeras in digital phase-locked loops [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2019 Digital phase-locked loops (DPLLs) are nonlinear feedback-controlled systems that are widely used in electronic communication and signal processing applications. In most of the applications, they work in coupled mode; however, a vast amount of the studies on DPLLs concentrate on the dynamics of a single isolated unit.
