Digitaliseringsmetoder refer to the processes and techniques used to convert analog information into a digital format. This conversion allows data to be stored, processed, and transmitted using computers and other digital devices. The specific methods employed depend heavily on the type of analog information being digitized.

For documents, photographs, and other physical media, scanning is a common method. Scanners use optical sensors to capture an image of the analog item and translate it into a digital file, such as a JPEG or PDF. Audio digitization typically involves converting sound waves into digital audio signals. This can be achieved using microphones connected to analog-to-digital converters (ADCs), which sample the sound at regular intervals and assign numerical values to each sample. Video digitization follows a similar principle, capturing visual information and converting it into a sequence of digital frames, often accompanied by a digital audio stream.

In scientific and industrial contexts, sensors are used to collect analog data from the physical world, such as temperature, pressure, or light levels. These sensors are usually coupled with ADCs to transform the continuous analog signals into discrete digital values. The choice of digitization method is crucial for ensuring the accuracy, integrity, and usability of the resulting digital data. Factors like sampling rate, bit depth, and file format all play significant roles in the quality of the digitized output.
