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 ) .

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.
What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
What is convert analog to digital convert?
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
What is the best signal processing either a analog signal processing?
Digital signal processing is the best compared to analog signal. It is because the digital signal is moreefficienterror freeimmune to noisethan an analog signal
What are analog and digital modes of operation of an instrument?
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission. In digital communication, the message signal to be transmitted is digital in nature. This means that digital communication involves the transmission information in digital form Example: ASK, FSK, PSK.
Why mostly periodic analog and non-periodic digital signal used in communication?
yes and no
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.
Difference between analog communication and digital communication?
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.
What converts a message from digital to analog and analog to digital?
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
What is encoding technique?
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
Analog & digital communication?
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission. In digital communication, the message signal to be transmitted is digital in nature. This means that digital communication involves the transmission information in digital form Example: ASK, FSK, PSK.
What are basic elements of digital signal processing?
The basic elements in digital signal processing are an analog to digital converter, digital signal processor, and digital to analog converter. This process can take an analog input signal, convert it to digital for processing and offer an analog output.
Where should analog to digital converter be placed?
where an analog signal is to be converted into digital signal,because in some applications we need digital signal where we have analog signal that is we use an A/D converter
What is an analog-to-digital converter?
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
How information is transmitted?
by analog to digital,digital to analog signal
Is PCM is an example of analog to digital?
No, Pulse Code Modulation is a communication method used to carry digital data but is not part of any analog to digital conversion. PCM is often used to carry audio data as a digital stream and therefore is the encoding used as the signal is first converted to a digital format.
