Digital synapse input signals which are temporally aligned with each other are converted to analog form for application to a neural net layer. Several digital synapse input signals can be written into digital memory at different times, to be read out in temporal alignment for conversion to analog form...http://www.google.fr/patents/US5247605?utm_source=gb-gplus-shareBrevet US5247605 - Neural nets supplied synapse signals obtained by digital-to-analog conversion of plural-bit samples
