and those don't hold for more random waveforms.
If your waveform is truly random, but of low bandwidth, you can build a rom table that sets the correct voltage increment so that a single filter, or perhaps two or three, connected with mosfet transmission gates (FET switches) will help you cope with the "glitches". ... Let your imagination run wild! ... Why 2500 samples and not some exact sum of a powers of 2, e.g. 2560? What you're doing, I suppose, is stroking at a 4 microsecond rate, but if, instead of stroking at a fixed rate, you stroke a fixed differential voltage, a single filter can help quite a bit. Further, if you segment your waveform in to portions of a single frequency, a filter tuned to attenuate that frequency can help with the glitches, too. Use your imagination! RE |
