NRL

A method and an apparatus to drive an analog signal into a sensory tissue. The apparatus includes an analog-to-digital converter converting an original analog signal to a digital signal at an analog-to-digital converter sample rate. The apparatus includes a digital transceiver communicating wirelessly with the analog-to-digital converter to receive the digital signal. The apparatus includes a digital data buffer receiving the digital signal from the digital transceiver. The apparatus includes a digital-to-analog converter communicating with the digital data buffer and converting the digital signal into a reconstructed analog signal at a digital-to-analog converter sample rate faster than the analog-to-digital converter sample rate, the analog signal comprising a plurality of intensity values. The apparatus includes a pixel clock matching the digital-to-analog converter sample rate. The apparatus includes a bio-interface array comprising a plurality of electrodes and operably proximate to the sensory tissue.
