ABSTRACT
Digital interfaces enable us to convert analog signals to a digital format that can be an input to a computer or a digital data storage system and, conversely, take digital data from a computer and convert it to an analog signal (voltage, current, light intensity, etc.). An analog-to-digital converter (ADC) performs the former task, while a digital-to-analog converter (DAC) undertakes the latter operation. There are many types of ADCs and DACs.
