1. A system, comprising:
a pulse generator configured to generate a plurality of voltage pulses;
a signal router operatively coupled to the pulse generator and a plurality of electrode sets each including one or more-electrodes,
the pulse generator configured to, prior to generating each voltage pulse of the plurality of voltage pulses, send a signal assigning an electrode set from the plurality of electrode sets to be activated,
the signal router configured to, in response to receiving the signal from the pulse generator prior to each voltage pulse of the plurality of voltage pulses, set one or more switches to deliver that voltage pulse as a biphasic pulse to the electrode set assigned by the signal from the pulse generator sent prior to generating that voltage pulse, and generate a trigger signal to trigger the pulse generator to generate that voltage pulse, the biphasic pulse including a positive phase, a negative phase, and an inter-phase delay between the positive and negative phases; and
a communication channel disposed between the signal router and the pulse generator, the communication channel configured to transmit the trigger signal for each voltage pulse of the plurality of voltage pulses to the pulse generator such that the pulse generator, in response to receiving the trigger signal, generates the voltage pulse for delivery to the electrode set assigned by the signal from the pulse generator sent prior to generating that voltage pulse.
