Questions tagged [discretization]

Discretization concerns the process of transferring continuous models and equations into discrete counterparts. This process is usually carried out as a first step toward making them suitable for numerical evaluation and implementation on digital computers.

Discretization is used everywhere in DSP (digital signal processing) to represent analog data, e.g. sound, in binary format to allow computer processing and editing.
