In this paper it is shown that a cellular neural network with an opposite-sign template can behave either as an amplitude or a frequency modulator. Firstly a brief information about these networks is given and then the amplitude and frequency surfaces of the generated quasi-sine oscillations are sketched with respect to various values of their cloning templates. Secondly it is proved that any of these types of modulations can be performed by only varying the template components without ever changing their structure. Finally a circuit is designed simulations are presented and performance of the proposed system is evaluated. The main contribution of this work is to show that both amplitude and frequency modulations can be realized under the same architecture with a simple technique specifically by treating the input signals as template components.eninfo:eu-repo/semantics/openAccessCellular neural networksNonlinear differential equationsAmplitude modulationFrequency modulationCircuit designArticle259272241WOS:00035117600001110.1007/s11063-014-9344-y2-s2.0-84924851591Q2Q2
