# What is meant by discrete signal?

## What is meant by discrete signal?

A discrete signal or discrete-time signal is a time series consisting of a sequence of quantities. Unlike a continuous-time signal, a discrete-time signal is not a function of a continuous argument; however, it may have been obtained by sampling from a continuous-time signal.

What is a discrete signal in electronics?

Discrete signals are either on or off, like a light switch. The applications and processes you are wanting to automate will determine the types of discrete devices you select. There are a variety of devices used to send and receive discrete on/off signals.

What are continuous and discrete signals?

A signal, of which a sinusoid is only one example, is a sequence of numbers. A continuous-time signal is an infinite and uncountable set of numbers, as are the possible values each number can have. between a start and end time, there are infinite possible values for time and instantaneous amplitude, .

### What is discrete value signal?

► Discrete-valued Signals. ► If a signal takes on values from a finite set of finite set. of possible values, it is said to be a discrete-valued. signals.

Are discrete signals binary?

Simple digital signals represent information in discrete bands of analog levels. All levels within a band of values represent the same information state. In most digital circuits, the signal can have two possible valid values; this is called a binary signal or logic signal.

What is difference between discrete and digital signal?

in discrete signal you can have any domain for each time(N),but in the digital signal you cant have any domain ,and you have standard value for each domain.

#### Is discrete signal a digital signal?

Discrete signals : periodic and fixed values in time axis and take any value in amplitude. Digital signals : periodic and fixed values in time axis and fixed values in amplitude. So, a discrete signal can’t be considered as an analog signal but not a complete digital signal.

Is a discrete signal *?

A discrete signal is one that is defined only at specific time intervals. If an continuous analog or digital signal is sampled at some rate, the sample set is a discrete signal. If the sample rate is 1.0 kHz, then there is a sample value every 1.0 milliseconds. This can be digital or analog.

What is the difference between discrete and continuous?

The key differences are: Discrete data is the type of data that has clear spaces between values. Continuous data is data that falls in a constant sequence. Discrete data is countable while continuous — measurable.

## Is digital and discrete the same?

A discrete time signal is quantised in time only, a digital signal is quantised both in time and amplitude. Neither a continuous amplitude discrete-time signal, nor a quantized discrete-time signal are digital signals.

What is the difference between digital and discrete?

Originally Answered: What is the difference between digital signal and discrete signal? A digital signal has discretized time axis and discretized amplitude axis. Whereas a discrete signal has a discrete time axis and a continuous amplitude axis. And both are non continuous signal.

Why do we need discrete signals?

Sampling discrete-time signals, i.e., using only every Nth sample of a sequence of samples, is useful for efficiently processing, transmitting, or storing information, if we can be sure that the sampling rate can be reduced without significant loss of information. This process is called decimation.
