From the web:

The DD-3 is a 12-bit digital delay with analog feedback and mixing stage. What this means is that everything in the pedal is analog, except the part that produces the actual delay. The analog signal is split, and a portion of it is sent to the delay chip (the rest ends up at the output stage, where it is joined with the delay signal). In the delay chip, the signal is slightly crudely converted into digital form (12 bits is not quite CD-quality, folks) and delayed. The delay chip then spits out an analog signal (delayed, of course), and a portion of that signal is sent back into the delay again (this is controlled by the feedback knob). So, for each pass the signal makes, it gets dirtier and dirtier, due to the repeated conversion process.
