AnDigital-to-Analogconverter(DACorD/Aconverter)functionistoconvert this digital values (in binary) back to analog values. Ananalog-to-digitalconverter(ADCorA/Dconverter)convertsananalog value to digital equivalent in a process called digitizing. Digital Voltages Has only 2 useful values that is high and low. Analog-to-Digital Converters (ADCs) Overview Definitions: Analog voltages Voltage that may vary continuouslythroughout some range.
