diskretiseerimine

Diskretiseerimine is a process of converting a continuous signal or a continuous range of values into a discrete set of values. This is a fundamental concept in many fields, including signal processing, control theory, and computer graphics. In essence, it involves sampling the continuous signal at regular intervals and quantizing the resulting samples. Sampling is the process of taking measurements of the signal at specific points in time or space. Quantization involves mapping each sampled value to one of a finite number of predefined levels. The result of diskretiseerimine is a sequence of discrete numbers that represent the original continuous signal. This discrete representation is essential for digital processing, as computers can only handle finite amounts of information. The choice of sampling rate and the number of quantization levels directly affects the accuracy and fidelity of the discrete representation. A higher sampling rate and more quantization levels generally lead to a more accurate representation but also require more storage and processing power. The opposite process, where discrete values are used to approximate a continuous function, is called interpolation. Diskretiseerimine is a necessary step before any digital analysis or manipulation of analog data can occur.
