Introduction
Most physical signals are analogue in nature. Sampling them is highly beneficial in various applications.
The significance of digital information processing systems, encompassing domains like radio, television, telephone, and instrumentation, continues to escalate. Technical merits often justify this preference, such as the high stability of parameters, excellent reproducibility of results, and enhanced functionality. Given that the external world is inherently "analogueue "
, a preliminary analogueue-to-digital conversion operation becomes imperative [6]. Analogue-to-digital conversion involves a sequence of three processes applied to the initial analogue signal:
Sampling : to discretize the signal.
Quantification : to assign a value to each sample.
Coding : to associate a code with each value.
