Need of data converters: It is often necessary that before processing the analog data, by a digital system, it should be changed to an equivalent digital form. Similarly, after processing the data, it may be desirable that the final result obtained in the digital form be converted back to the analog form. Therefore, data converters are necessary in digital systems. A combinational digital circuit which converts the one form of data into the other or vice versa is called as data converter.
