Digitaalsignaale

Digitaalsignaale refers to the Estonian term for digital signals. A digital signal is a signal that represents data as a sequence of discrete values. This is in contrast to an analog signal, which represents data as a continuous wave. Digital signals are characterized by their binary nature, typically using two distinct states, often represented as 0 and 1, to encode information.

The creation of digital signals involves a process called digitization. Analog information, such as sound or images, is sampled at regular intervals and then converted into discrete numerical values. These values are then represented in a binary format. This conversion allows for robust transmission and storage, as digital signals are less susceptible to noise and distortion compared to their analog counterparts. Error correction techniques can also be more easily implemented with digital signals.

Digital signals are fundamental to modern electronic devices and communication systems. They are used in everything from computers and smartphones to digital television and the internet. The ability to manipulate, process, and transmit digital signals with high fidelity has revolutionized how information is handled and shared globally. The discrete nature of digital signals also facilitates complex algorithms and data processing, enabling advanced functionalities in various technologies.
