What is an analog signal?
An analog signal is a continuous signal that contains time-varying quantities. Unlike a digital signal, which has a discrete value at each sampling point, an analog signal has constant fluctuations. netonplus.com
Differentiate between an analog and a digital electromagnetic signal?
1. Digital Signal is non-continuous signal where as analog is continuous signal 2. Digital signal contain only two value that is 0 or 1,or high or low where as analog contain all the values in it's time interval 3.Chance of attenuation in analog is more then digital signal
Difference between discrete and digital signal?
THE TERM CONTINUOUS SIGNAL AND DISCRETE SIGNAL CLASSIFY THE SIGNALS ALONG THE TIME (i.e. horizontal axis) where as THE TERM ANALOG AND DIGITAL SIGNAL CLASSIFY THE SIGNAL ALONG THE AMPLITUDE (i.e vertical axis) we often confuse our-self with continuous time and analog signals. An analog signal is a signal which can take any amplitude in continuous range that is signal amplitude can take infinite values on the other hand a digital signal is one whose amplitude can take only finite numbers of values

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.
Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
Is there any difference between an analog signal and a wave signal?
A Digital Signal can have one of two values, 1 or 0. An Analogue signal can have any value between 1 and 0. Digital signals are better for sending information as if the signal is somewhat distorted, it is still easily recognisable. Vinyl Record use analogue. Cds use Digital
What is the difference between analog and digital in very simple English?
Analog signals represent values with a continuously variable level. The signal has an infinite number of possible levels. Because the signal is infinitely variable, it can be affected by outside interference as well as by the circuits that carry and process the signal. These are the sources of noise and distortion. A system that handles analog information must be able to operate at the highest frequency that the signal will use. For audio, that is typically 20KHz and for video, in the region of 10MHz. A digital signal represents values in discrete steps and is often shown as a numeric value. The signal has a limited number of steps and there is no way to represent any intermediate values. The limitation in the number of steps is in itself a source of distortion but the nature of digital signals is that they are resistant to distortion and noise so the signal will not be degraded further. As the number of possible values increases, so the distortion caused by digitizing the signal will reduce. A digital system typically has to operate at far higher frequencies than its analog counterpart. Using audio signals as an example, a typical digital signal will capture a 16 bit value 44000 times each second. The frequency response of circuits handling the data will need to be in the region of 700KHz rather than the 20KHz for an analog signal.
What do you mean by analog signal and digital signal?
Digital signals have discrete encoded states that they switch between. They can only assume the defined encoded values. Errors can often be easily detected and sometimes corrected.Analog signals are continuous and change smoothly from one value to another, passing through all intermediate values. There is no way to identify errors.
Why is digital technology preferred to analog technology in communications technology?
Why digital communications and what its advantages over analog communication ,first you have to know what is the difference between analog signal and digital signal. Analog signal analog signal is continuous time signal i.e. it has a value at any moment of time and it has infinite number of valus , such as dinusoidal signal ,you can substitute X with any value and you will have an value in Y in the follwing sin relation Y=sin(X). 1-Noise and destortion immunity:-when analog signal is transmitted in free space for long distances it will be distorted and no an ideal recovery done in receiver to recover the exact signal which transmitted ,but in digital communication digital signal consist of 2 levels only zero or one (not like the analog one , it has infinite numbers of values or levels at each period of time),so digital signal can be recovered easily and excactly like transmitted one. Hint : Device that used to pattially recover the analog signal after a certain distance is called repeater ,from its name it receives transmitted analog signal and filter it and amplify it and transmitt it),but in digital transmission it is different ,the device used for recovering digital signal which transmitted from acertain distance is called regenerative repeaters ,it receives transmitted digital signal and recover it to regenrate a new exact signal like received one then retransmitt it for further distance. 2-More privacy and security due to encryption. 3-Error detection techniques can be used and correction as well. 4-Easy for processing and applying multiplexing techniques. 5-Low cost. 6-Transmission rate can be changed easily. 7-Digital hardware implementation is flexible and permits the use of micrprocessors, digital switching elements and layer scale.
