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 is quantization error?
Quantization error is the difference between the actual analog signal and the quantized digital representation of that signal. It occurs when an analog signal is converted into a digital form by rounding off the signal values to the nearest available digital value. This error can introduce inaccuracies in the signal representation.
How did analog become digital?
Analog signals, such as sound or light, are converted into digital form through a process called analog-to-digital conversion. This process involves quantizing the continuous analog signal into discrete, digital values represented by binary numbers. Once in digital form, the signal can be processed, stored, and transmitted more efficiently and accurately.
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 digital signal frequency 0 Hz?
No, a digital signal does not have a specific frequency like an analog signal. Digital signals are represented by discrete values at specific time intervals and are typically transmitted using square waves with a fundamental frequency determined by the data rate.
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.
