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