What does digital data mean?
A digital signal is a physical signal that is a representation of a sequence of discrete values (a quantified discrete-time signal), for example of an arbitrary bit stream, or of a digitized (sampled and analog-to-digital converted) analog signal. The term digital signal can refer to either of the following:any continuous-time waveform signal used in digital communication, representing a bit stream or other sequence of discrete valuesa pulse train signal that switches between a discrete number of voltage levels or levels of light intensity, also known as a line coded signal or baseband transmission, for example a signal found in digital electronics or in serial communications, or a pulse code modulation (PCM) representation of a digitized analog signal.A signal that is generated by means of a digital modulation method (digital passband transmission), to be transferred between modems, is in the first case considered as a digital signal, and in the second case as converted to an analog signal.
Signal cable for 0 to 10 volts signal?
bit means a signal that goes around every where.
Definition of digital signal encoding?
encoding means conversion of data into bit strem..
Why digital signals has infinite frequencies?
Some might equate a digital signal frequency as the bit rate per second. However, this measures the clock rate that encodes and decodes the digital pulse train. If you looked at frequency as being the repetition rate of a unique waveform and assumed that the digital pulse train never repeated the frequency would be the cycles of the repeating single over time. By this measure a signal that didn't repeat would go on continually as it tried to become infinite. There are a lot of assumptions made in this definition and the results are not very useful unless it is a thought experiment or a test of some sort.
Is it possible that the pulse rate is equal bit rate?
Yes, it is possible for the pulse rate to equal the bit rate, particularly in digital communication systems where each pulse represents a single bit of information. In such cases, the pulse rate, measured in pulses per second (hertz), directly corresponds to the bit rate, measured in bits per second. However, in more complex systems, multiple bits can be represented by a single pulse, leading to scenarios where the pulse rate and bit rate differ. Thus, while they can be equal, it is not a universal rule.
A digital signal has a bit rate of 4000bps What is the duration of each bit bit interval?
Answeryes it is AnswerRb = 4000 bpsTb = 1/Rb = 250 μsKotsos
Why is digital signal immune to noise?
Digital signals can gather information with noise because the information component is determined whether its presence or absence a data bit. Digital signals can processed by digital circuit components they are cheaper an easily to create in many components on a signal chip.
How does a digital countdown timer works?
a digital countdown timer is simply a digital synchronous counter consisting of registers and flip flops example :to count the number from 0 to 15 we require a four bit synchronous counter which will pass to sixteen stages continuously with shifting from one stage to other after every clock pulse and the cycle continues
Why it is generly true that a digital signal required high bandwidth than analog signal?
A: Analogue signal Direct voltage that varies in the low spectrum of frequency on digital signal the information is deciphered in micro seconds therefore the frequency must be hi the higher the better.
What the bit interval and counterpart in analog signal?
The bit interval, or bit duration, is the time taken to transmit one bit of data in a digital signal, typically measured in seconds. In analog signals, the counterpart to the bit interval can be considered as the time constant or the time period of a waveform, which defines how long each cycle of the signal lasts. While digital signals represent discrete values, analog signals vary continuously, and their characteristics are defined by parameters such as frequency and amplitude rather than distinct bit intervals.
What is the digital to digital signal encoding technique?
The digital encoding techniques are of two types--Polar and Bipolar. The polar encoding are--RZ(Return to Zero), NRZ (No RZ) , Manchester and Differential Manchester. Bipolar encoding are--AMI ( Alternate Mark Inversion) and BnZS ( Bipolar n Zero Substitution).
