We show experimental evidence for vibrational resonance in the single Chua's circuit and undamped signal propagation of a low-frequency signal in the system of n-coupled Chua's circuits where only the first circuit is driven by the biharmonic signal. In the single circuit, we illustrate the mechanism of vibrational resonance and the influence of the biharmonic signal parameters on the resonance. In the n(=75)-coupled Chua's circuits enhanced propagation of low-frequency signal is found to occur for a wide range of values of the amplitude of the high-frequency input signal and coupling parameter. The response amplitude of the ith circuit increases with i and attains a saturation. Moreover, the unidirectional coupling is found to act as a low-pass filter. <\/jats:p>","DOI":"10.1142\/s0218127413501897","type":"journal-article","created":{"date-parts":[[2013,12,12]],"date-time":"2013-12-12T21:07:05Z","timestamp":1386882425000},"page":"1350189","source":"Crossref","is-referenced-by-count":35,"title":["EXPERIMENTAL EVIDENCE FOR VIBRATIONAL RESONANCE AND ENHANCED SIGNAL TRANSMISSION IN CHUA'S CIRCUIT"],"prefix":"10.1142","volume":"23","author":[{"given":"R.","family":"JOTHIMURUGAN","sequence":"first","affiliation":[{"name":"Centre for Nonlinear Dynamics, School of Physics, Bharathidasan University, Tiruchirappalli-620 024, Tamilnadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"THAMILMARAN","sequence":"additional","affiliation":[{"name":"Centre for Nonlinear Dynamics, School of Physics, Bharathidasan University, Tiruchirappalli-620 024, Tamilnadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"RAJASEKAR","sequence":"additional","affiliation":[{"name":"School of Physics, Bharathidasan University, Tiruchirappalli-620 024, Tamilnadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
