A system for decreasing output power required to produce an output signal based on persistence of perception characteristics. The system includes a circuit configured to receive a perception signal at an input. The circuit is also configured to output a portion of the input perception signal when the circuit is receiving power output a zero amplitude signal when the circuit is not receiving power. The system also includes a switch configured to provide power to the circuit for a first interval of time and cut power to the circuit for a second interval of time contiguous to the first interval of time.
