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
which repeat periodically. after time T its charactristics are repeated is called periodic signal.
Signals are aperiodic because they are not repetitive.
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.
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
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
Analog signals are continuous while digital signals are discrete
Signals are aperiodic because they are not repetitive.
Digital signals
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
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.
The difference between energy and power signals...power signals have infinite energy but finite power..
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.
The difference between slow and fast FHSS is the speed of the transmitting radio signals. Both have signals that are difficult to intercept.
Here Energy signals are limited but power signals can exist to infinite distance. Non periodic signals are energy signals while power signals are periodic.
What the difference between envelop and coherent detection of AM signals
Examples of the periodic signals include exponential and sinusoidal signal.
yes
A stellar source of periodic radio signals is called quasar. This runs off of radio waves.
