Abstract:
    A system, apparatus, method and article to emulate a filter using digital elements are described. The apparatus may include a digital-to-analog converter (110, 500) having an impulse response emulator (202, 510), the impulse response emulator (202, 510) to receive multiple digital signals each having a predetermined waveform, and convert a sequence of bits from each digital signal to a predetermined analog waveform corresponding to the sequence of bits. In preferred embodiments, the sequence of bits can be converted using a lookup table (506) or a digital filter (704).
