What's the difference between Analog and Digital? Analog and digital signals are used to transmit information, usually through electric signals. In both these technologies, the information, such as any audio or video, is transformed into electric signals. The difference between analog and digital technolo...
Quite simply, analog-to-digital conversion changes a continuously variable (analog) signal to a multi-level (digital) signal, without changing its content. This is accomplished with an analog-to-digital converter (ADC). The input consists of a voltage (also called electromotive force); examples include waveforms representing human speech and signals from a television camera. While the input varies among an infinite number of values, the converter's output is a defined level or state in a power of two. This entry briefly explains the process and includes links to related terms.
