Furthermore, experiments are developed for teaching electronic systems that can be used for novel filtering concepts. The frequency range in which they are tested is from $20\;{\rm Hz}$ to $20\;{\rm kHz}$, due to the audio spectrum comprised in this frequency range. The node associated with the capacitor and Chuaʼs diode is used as input, and the node for another capacitor and the coil is used as output, thereby establishing one input–output relationship for each system case given by the piecewise linear functions. The experimental result shows that Chuaʼs circuit behaves as a bandpass filter-amplifier, with a maximum frequency around $3\;{\rm kHz}$ and bandwidth between $1.5\;{\rm kHz}$ and $5.5\;{\rm kHz}$. The results presented in this paper can motivate engineering students to pursue applications of novel electrical circuits based on topics that are of potential interest in their future research studies." dc.rights Attribution-NonCommercial-NoDerivatives 4.0 Internacional dc.rights.uri http://creativecommons.org/licenses/by-nc-nd/4.0/ dc.subject Filters dc.subject Chua´s circuit dc.subject Piecewise linear functions dc.subject Analog electronics dc.subject.classification MATEMÁTICAS dc.title Chua´s circuit and its characterization as a filter dc.type article dc.identifier.doi https://doi.org/10.1088/0143-0807/35/6/065018 dc.rights.access Acceso Abierto
