Digital electronics‚ or digital (electronic) circuits‚ represent signals by discrete bands ofanalog levels‚ rather than by a continuous range. All levels within a band represent the same signal state. Relatively small changes to the analog signal levels due to manufacturing tolerance‚ signal attenuation or parasitic noise do not leave the discrete envelope‚ and as a result are ignored by signal state sensing circuitry. In most cases the number of these states is two‚ and they are represented by

digital (usually binary) code to an analog signal (current‚ voltage‚ or electric charge). An analog-to-digital converter (ADC) performs the reverse operation. Signals are easily stored and transmitted in digital form‚ but a DAC is needed for the signal to be recognized by human senses or other non-digital systems. A common use of digital-to-analog converters is generation of audio signals from digital information in music players. Digital video signals are converted to analog in televisions and
