Continuous-time signals are often referred to as continuous signals. A second important distinction is between discrete-valued and continuous-valued.

Particularly in digital signal processing , a digital signal may be defined as a sequence of discrete values, typically associated with an underlying continuous-valued physical process. In digital electronics , digital signals are the continuous-time waveform signals in a digital system, representing a bit-stream. Another important property of a signal is its entropy or information content.

Analog and digital signals[ edit ] A digital signal has two or more distinguishable waveforms, in this example, high voltage and low voltages, each of which can be mapped onto a digit. Characteristically, noise can be removed from digital signals provided it is not too large. Two main types of signals encountered in practice are analog and digital. The figure shows a digital signal that results from approximating an analog signal by its values at particular time instants.

Digital signals are quantized , while analog signals are continuous. Main article: Analog signal An analog signal is any continuous signal for which the time varying feature of the signal is a representation of some other time varying quantity, i. For example, in an analog audio signal , the instantaneous voltage of the signal varies continuously with the sound pressure. It differs from a digital signal , in which the continuous quantity is a representation of a sequence of discrete values which can only take on one of a finite number of values.

An analog signal uses some property of the medium to convey the signal's information. For example, an aneroid barometer uses rotary position as the signal to convey pressure information.

In an electrical signal, the voltage , current , or frequency of the signal may be varied to represent the information. Any information may be conveyed by an analog signal; often such a signal is a measured response to changes in physical phenomena, such as sound , light , temperature , position, or pressure. The physical variable is converted to an analog signal by a transducer. For example, in sound recording, fluctuations in air pressure that is to say, sound strike the diaphragm of a microphone which induces corresponding electrical fluctuations.

The voltage or the current is said to be an analog of the sound. Main article: Digital signal A binary signal, also known as a logic signal, is a digital signal with two distinguishable levels A digital signal is a signal that is constructed from a discrete set of waveforms of a physical quantity so as to represent a sequence of discrete values.

Other types of digital signals can represent three-valued logic or higher valued logics. Alternatively, a digital signal may be considered to be the sequence of codes represented by such a physical quantity. Digital signals are present in all digital electronics , notably computing equipment and data transmission.

A received digital signal may be impaired by noise and distortions without necessarily affecting the digits With digital signals, system noise, provided it is not too great, will not affect system operation whereas noise always degrades the operation of analog signals to some degree.

Digital Processing Of Speech Signals

The resulting stream of numbers is stored as digital data on a discrete-time and quantized-amplitude signal. Computers and other digital devices are restricted to discrete time. Time discretization[ edit ] Discrete-time signal created from a continuous signal by sampling One of the fundamental distinctions between different types of signals is between continuous and discrete time.

In the mathematical abstraction, the domain of a continuous-time CT signal is the set of real numbers or some interval thereof , whereas the domain of a discrete-time DT signal is the set of integers or some interval.
