Analogue to digital converters (ADCs) are devices that convert analogue input signals into a digital output signal, for example a sound captured from a microphone or light entering a digital camera. These analogue inputs are then converted into a digital signal output as either sound from a speaker or a picture in a camera.
ADCs sample the input signals at specific points in time which reduces the allowable bandwidth of the input signal for increased efficiency.
Audio analogue to digital converters captures and converts analogue sounds into digital signals using a mathematical function called quantisation. This conversion occurs periodically instead of continuing to minimise noise generation.
Video analogue to digital to converters are a high-frequency low- to medium-resolution type that is used to convert analogue video data into digital video signals such as displays on digital cameras.
General Purpose ADCs are considered the base type of ADC un of the mill ADCs are used to convert analogue signals to digital signals in equipment such as temperature sensors.
The most widely used types of ADCs are:
Audio ADCs are widely used in applications such as:
Video ADCs are used in:
General Purpose ADCs are used primarily in applications such as:
