Analog to Digital Conversion

Learning objectives

To describe the succession of steps in the conversion of an analog signal to a digital file.
To illustrate the advantage of increasing the number of bits and the sampling rate.
To show that increased precision results in an increase in the size of the output file.

The digitization of an analog signal is carried out by taking several samples and translating them into binary code. The series of codes thus obtained are then regrouped in a digital file. The advantage of such digitization lies in the ability of such file formats to undergo processing by a computer. In order to obtain a digitization that corresponds to the original analog signal one must gain precision.

To do this, it is sufficient to increase the sampling frequency and decrease the pace of quantization.
