Abstract

SANTILLAN, M.. Synchronization dynamics of two mutually coupled 555-IC based electronic oscillators. Rev. mex. fis. [online]. 2018, vol.64, n.2, pp.107-115. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.64.107.

We designed and implemented an electronic oscillatory system consisting of two mutually coupled oscillators (each one based on the 555timer IC working in astable mode), and investigated its synchronization dynamics. For that purpose, we characterized the phase-locking rhythms achieved in a large set of values of the uncoupled frequency ratio and of the coupling strength between both oscillators. We further developed an ODE mathematical model that qualitative reproduces the obtained experimental results and provides further insight into the system behavior.

Keywords : Two-oscillator synchronization; relaxation oscillator; diffusive coupling.
