Phenomenon of isolated jump resonance and its applications
S.S. Lamba, R.J. Kavanagh · Proceedings of the Institution of Electrical Engineers · 1971
Under certain conditions of periodic excitation where both the input amplitude as well as the input frequency are varying, nonlinear multimodal systems can be forced exhibit a response in which jumps down occur for both an increase as well as a decrease in input frequency from a median value. This interesting phenomenon is termed ‘isolated jump resonance’. Systems of this type exhibit considerable sensitivity to changes in input frequency or amplitude at the occurrence of the jumps. Application of such systems as sensitivie detectors of frequency deviations in a periodic signal are proposed. A discussion of design considerations is given and a description is included of a system which has been constructed.
