Analog and Digital Conversion/Hold Circuits
Zero Order Hold
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 Hold
Fractional Order Hold
