A signal which repeats itself after a specific interval of time is called periodic signal. A signal which does not repeat itself after a specific interval of time is called aperiodic signal.
A signals that repeats its pattern over a period is called periodic signal,
A signal that does not repeats its pattern over a period is called aperiodic signal or non periodic.
Both the Analog and Digital can be periodic or aperiodic. but in data communication periodic analog sigals and aperiodic digital signals are used.
•Non-periodic signal
•pattern not repeated over time
• Both analog and digital signals can b
e periodic or non-periodic
--(a) shows periodic continuous signal (sine wave)
--(b) shows periodic discrete signal (square wave)
•In data comm., we commonly use periodic analog signals and non-periodic digital signals

Please fill this blank Almost all the digital signals are Options1 Periodic Option 2 A-periodic?
Signals are aperiodic because they are not repetitive.
What is phase difference?
A phase difference between two periodic signals is the time difference between two corresponding points on each signal. This time difference is usually measured in degrees or radians, but can be given as a unit of time as well.
Difference between inband and out of band signaling?
In in- bandsignalling , the control and management signals travles along with the data signals where as in out of band signalling the data and control signals travels in different channels
What is the difference between digital and analog signals in tabular form?
If we discuss the different between these two forms of the signals that is; analog and digital then we should discuss it in different aspects such as working, their architectures, pros and cons as well. The major differences among the two signals are listed below
Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
What signals are likely to be aperiodic?
Signals that are likely to be aperiodic include impulse functions, noise signals, and random signals. These signals do not exhibit a repeated or periodic pattern over time.
Please fill this blank Almost all the digital signals are Options1 Periodic Option 2 A-periodic?
Signals are aperiodic because they are not repetitive.
Difference between linear and circular convolution?
circular convolution is used for periodic and finite signals while linear convolution is used for aperiodic and infinite signals. In linear convolution we convolved one signal with another signal where as in circular convolution the same convolution is done but in circular pattern ,depending upon the samples of the signal
What is phase difference?
A phase difference between two periodic signals is the time difference between two corresponding points on each signal. This time difference is usually measured in degrees or radians, but can be given as a unit of time as well.
Electric signals whose values change smoothly over time are called?
Repetitive signals are referred to as periodic signals, while signals that constantly change are known as non-periodic signals. A still picture is analogous to a periodic signal, while a movie is analogous to a non-periodic signal. Synchronous and Asynchronous Signals.
What is difference between a coherent detector and envelop detector?
What the difference between envelop and coherent detection of AM signals
What is the difference between an electical engineer and an electronic engineer?
Power vs Signals
What is the difference between television signals now and then?
now they are better now they are better
What are examples of periodic signals?
Examples of the periodic signals include exponential and sinusoidal signal.
Are transmitted cellphone signals periodic?
yes
How does differential pulse code modulation lower the bit rate of transmitted signals?
It signals the difference between successive sample sizes
What is a stellar source of periodic radio signals called?
A stellar source of periodic radio signals is called quasar. This runs off of radio waves.
