DIGITAL SIGNAL Meaning and
Definition
-
A digital signal refers to a representation of information or data in a discrete form, utilizing symbols or digits that can have only a limited number of distinct values. It is a digital representation of analog signals, which are continuous and vary continuously with time. Digital signals are used in various electronic devices, communication systems, and computing technologies.
In a digital signal, data is encoded into binary digits, commonly known as bits. Each bit can have two distinct states, typically represented as 0 or 1. These binary digits are the building blocks for creating digital signals. They can be used to convey different types of information like numbers, text, images, or audio.
Digital signals have numerous advantages over analog signals. They are less susceptible to noise and interference, making them more reliable for long-distance transmission and storage. Digital signals can also be easily manipulated, processed, and analyzed using various digital techniques and algorithms.
Digital signal processing (DSP) is a field of study that focuses on the manipulation and analysis of digital signals. DSP techniques allow for filtering, compression, encryption, and other operations to be performed on digital signals. Digital signal processing is widely used in applications such as image and video processing, audio encoding and decoding, telecommunications, and control systems.
Overall, a digital signal is a discrete representation of data using binary digits, enabling reliable transmission, storage, and manipulation of information in various electronic systems and communication technologies.

Etymology of DIGITAL SIGNAL
The word "digital" comes from the Latin word "digitus", which means finger or toe. In the late 15th century, it was used to refer to numerical digits. The term "signal" originated from the Latin word "signum", meaning a sign, mark, or indication.
The combination of these two terms, "digital signal", emerged in the mid-20th century with the development of digital technology. It refers to a type of signal that represents information as a sequence of discrete values or digits, typically represented by binary digits (0s and 1s). The term evolved to describe signals that are processed, transmitted, or stored digitally, as opposed to analog signals, which represent information using continuous physical quantities.
