Abstract
According to one aspect of the present invention, this invention implements a low latency, wide bandwidth method and system for converting a numeric digital values into a pulse density modulated analog output signals. Such output signals having their lowest output frequency much closer to the system clock frequency, thus enabling wider bandwidth and simpler implementations than with traditional approaches. This method is based in part on an adaptation of Bresenham's Line Drawing Algorithm.
