Analog-to-Digital Conversion

Microphones produce analog voice, while cameras provide analog video, both of which are processed as analog data. Analog to digital conversion is required to transport this analog data via digital impulses. Digital data is discrete, but analog data is a continuous stream of data in the waveform. Pulse Code Modulation(PCM) is used to convert analog waves into digital data (ie. Analog to Digital Conversion). One of the most often used methods for converting analog data to digital form is PCM. There are three steps to…
