Analog and Digital Conversion/Hold Circuits

Hold CircuitsEdit

Zero Order HoldEdit

The majority of DACs have "zero order hold" in their output. After feeding the data into the DAC, the DAC output jumps to a new output voltage. The DAC holds that output voltage constant for the entire sampling time, until a new value is fed into the DAC and the DAC output jumps to that new value.

First Order HoldEdit

Fractional Order HoldEdit
