What is ADC & How is ADC Processed?
The mean of ADC stands for Analogues to Digital Converter. The process of analogue to digital conversion is outlined in some ways. Computers individually process digital information, they command digital input, therefore, if an analogue input is distributed to a laptop, ADC is needed. The terminology of analogue is defined has a nonstop valued signal, such as temperature or speed, with unlimited potential values in between, in another case, an analogue signal can be used to measure changes in light, sound, pressure or temperature. An analogues microphone can transform sound waves into an analogue signal. The terminology of digital is also labelled as a signal refer to an electrical signal that is transformed into a pattern of bits. A digital signal has a separate value at each sampling point. “ADC may also be used to converts audio streams. For examples, if you want to record sounds from a microphone, the audio must be converted from the microphone’s analogue signal into a digital signal that the computer can understand” (Techtermscom, 2018). This is the reason why sound cards have an analogue audio input also demand an ADC that transfers the incoming audio signal to a digital format.

Start My OrderSampling is a method of taking an adequate range of separate values at a point on a waveform that will state the form of the wave. “The sampling frequency (or sample rate) is the number of samples per second in a sound, For example: if the sampling frequency is 44100 hertz, a recording with a duration of 60 seconds will contain 2,646,000 samples”(Humuvanl, 15 April 2015). I noticed the more samples you take, the more accurately you will outline the waveform. It transfers an analogue signal into strings of impulses, all indicating amplitude of the signal at a given point.
What is Quantization?
Quantization is a method that transfers sampled signal into an estimated quantized signal which contains only a limited number of voltage levels. Each sampled value at the input of the quantizer is estimated to the closest average voltage level. “the process of digitizing the range is called quantization”(sisuutee, unknown).

This are sampling and quantization diagram examples:-
Diagram1 “Figure 5.8 Quantized wave”(Digital Sound & Music,2014)
In this diagram show how an analog signal gets quantized. The blue line represents analog signal as the red one represents the quantized signal. Both sampling and quantization result in the loss of information. The value of a quantizer output depends upon the number of quantization levels used. The separate amounts of the quantized output are called representation level. The spacing between the two adjacent representation levels is called a step-size.
