Analog to Digital Converter (ADC)

•Analog quantity may be voltage, temperature, sound, speed, audio etc. it is information or signal.

•Digital means it is in binary form (1 and 0) 1 means on and 0 means off.

•Converter is a device.

•Analog to Digital Converter (ADC) is use for converting analog signal into digital form.

•Most of the data is in analog form but most data processing is done using digital computers.

•So for processing and/or modifying signals we need to convert it in digital form.

•Pulse Code Modulation (PCM) technique method is use to digitally represent discrete analog signal.

•PCM consists of three stages one is sampling second is quantization and third is binary encoding.

•The sampling measures the amplitude of the signal at different interval.

•Quantization is the process of converting the sampled continuous large set of input value to small countable discrete value.

•Binary Encoding is assigning of binary equivalent to each state of output.

•There are four types of ADC one is counter type second is integrating or dual scope third is parallel or flash fourth is successive approximation.

•Examples of Analog to Digital (A to D) converters are microphone (converts analog audio signal to digital form), Voltmeter (converts analog voltage signal into digital), Scanner and camera (converts analog image into digital form), digital speedometer (converts analog speed into digital form) etc.
