Recently, a novel mixed synchronization phenomenon is observed in counter-rotating nonlinear coupled oscillators (Prasad in Chaos Solitons Fractals 43:42-46, 2010). In mixed synchronization state: some variables are synchronized in-phase, while others are out-of-phase. We have experimentally verified the occurrence of mixed synchronization states in coupled counter-rotating chaotic piecewise Rossler oscillator. Analytical discussion on approximate stability analysis and numerical confirmation on the experimentally observed behavior is also given.
