How Do Analogue to Digital Converters Work?
Analogue Signals Analogue signals are transmitted continuously. VCRs, walkie-talkies and turntables use analogue signals. They are usually sent as electrical impulses, but in the case of walkie-talkies, they are transmitted via radio waves. Digital Signals A digital signal is composed of a stream of binary data. Binary is a computer language that consists of a series of 0s and 1s that are interpreted by digital devices. Digital cable, HD radio and MP3 players utilize digital signals to create output. Conversion During conversion, the analogue signal is passed to a device for interpretation. A computer’s audio input, for example, accepts an analogue signal such as one from a microphone or tape player. The electronic impulses of this signal are interpreted by the analogue to digital converter (ADC). The ADC converts the interpreted analogue signal to a stream of binary data before passing it to the appropriate program. Sampling When used for audio, the ADC determines the quality of the r
