In electronics, an A\/D converter (analog-to-digital converter or ADC) converts an analog signal into a digital signal. The analog signal might be for instance a sound picked up by a microphone, light entering a digital camera as well as an analog voltage or current signal. The following paragraphs explain the working principle behind an A\/D converter and illustrate the A\/D conversion by DEWETRON.<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n\n

What do the terms \u201canalog\u201d and \u201cdigital\u201d mean?<\/h2>\n
\n

The terms \u201canalog\u201d and \u201cdigital\u201d relate to the way of representation of the signal. While an analog signal describes the course of a continuous variable over time, a digital signal is a discrete signal that transmits the information in a binary form (stored in the form of ones and zeros). As digital electronic equipment (e.g. microcontroller) cannot process analog signals, A\/D converters find use to translate our analog world into digital values.<\/p>\n

A\/D conversion process<\/h2>\n

As already said, the A\/D converter converts an analog input signal (in the test and measurement industry mostly voltages) into a digital form. Thereby, the conversion mainly consists of three steps:<\/p>\n
