A periodic signal is a signal that repeats itself over a fixed period of time such as a sinusoidal, square, triangular or sawtooth waveform. So, basically they are used in almost every application of electrical engineering. These periodic waveforms, are also responsible for driving oscillators which is very important in computer applications where a CPU may need to operate according to the clock speed that is determined by the oscillator.

What is the difference between periodic and aperiodic signals?
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.
Please fill this blank Almost all the digital signals are Options1 Periodic Option 2 A-periodic?
Signals are aperiodic because they are not repetitive.
In Fourier transformation and Fourier series which one follows periodic nature?
The Fourier series can be used to represent any periodic signal using a summation of sines and cosines of different frequencies and amplitudes. Since sines and cosines are periodic, they must form another periodic signal. Thus, the Fourier series is period in nature. The Fourier series is expanded then, to the complex plane, and can be applied to non-periodic signals. This gave rise to the Fourier transform, which represents a signal in the frequency-domain. See links.
Why we use periodic analog and non periodic digital signal in communication?
In data communication computer use periodic analog signal because it Need Less Bandwidth. So, by using Periodic Analog Signals it is easy to select the Medium through Which data is travelled otherwise it is Much Difficult (aprox. Impossible ) .
Why FDM is for analog signals and TDM is for digital signals?
FDM stnds for frequency division multiplexing and it is used only in case of analog signals because analog signals are continuous in nature and the signal have frequency. TDM-stands for time division multiplexing and it is used only in case of digital signals because digital signals are discrete in nature and are in the form of 0 and 1s. and are time dependent.
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.
Define energy and power signal?
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 are examples of periodic signals?
Examples of the periodic signals include exponential and sinusoidal signal.
What is the difference between periodic and aperiodic signals?
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.

Are transmitted cellphone signals periodic?
yes
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.
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
Why is the need for circular convolution?
for finding convolution of periodic signals we use circular convolution
Why neon is used in warning signals?
neon is used for warning signals
Membrane protein used to receive signals?
Receptors are proteins on the cell membrane that are used to receive signals
