3.5.7+Digital+&+Analogue+Data+Interconversion

=__** Digital and Analogue Data Interconversion **__=


 * More on how to see how Analogue to digital conversion works can be found on pages 3.5.6 (Digital & Analogue Data) and 3.5.8 Conversion Applications **


 * In order for computers(digital) to measure the world around it(analogue) the computer needs to use a ADC (or Analogue to Digital Converter)
 * In order for us to use computers we need ADCs (or Digital to Analogue Converters) that convert digital data to analogue data that we can perceive

__**Examples**__
 * A modem that is connected to a system should provide the system with internet
 * If the modem gets in a analogue signal through a phone line, then it needs to have a ADC so the system can understand the signal
 * If a computer wants access to the internet via a phone line the modem converts digital outputs from the computer to analogue signals
 * Sensors that record analogue data need an ADC, or the system needs one, in order to make the data useful for the system.
