We report on a theoretical study of transport properties of two coupled
Josephson junctions and compare two scenarios for controlling the
current-voltage characteristics when the system is driven by an external biased
DC current and unbiased AC current consisting of one harmonic. In the first
scenario, only one junction is subjected to both DC and AC currents. In the
second scenario the signal is split -- one junction is subjected to the DC
current while the other is subjected to the AC current. We study DC voltages
across both junctions and find diversity of anomalous transport regimes for the
first and second driving scenarios.
