Analog signals are continuous where digital signals are discrete. Anolog signals are continuously varying where digital signals are based on 0's and 1's (or as often said------- on's and off's). As an analogy, consider a light switch that is either on or off (digital) and a dimmer switch (analog) that allows you to vary the light in different degrees of brightness. As another analogy, consider a clock in which the second hand smoothly circles the clock face (analog) versus another clock in which the second hand jumps as each second passes (digital). Digital computers work with a series of 0's and 1's to represent letters, symbols, and numbers. In addition, numbers are represented by using the binary code (where only 0's and 1's are used).
Number Binary equivalent
1----------------------------------------------1
2---------------------------------------------10
3---------------------------------------------11
4--------------------------------------------100
5--------------------------------------------101
6--------------------------------------------110
7--------------------------------------------111
8-------------------------------------------1000
and so on. So each number (that we are accustomed to, such as 5) is represented by 0's and 1's. Morse Code uses dits (or dots) and dashes. Digital signals are similar to Morse code. The signal is either a dit or a dash for Morse code and it is either a 0 or 1 for digital. A series of these dits and dashes might represent SOS to a navy radio man, and a series of 0's and 1's might represent the question mark to a computer.

∙ 9y agoThe particular difference involving analog and digital engineering is of which in analog technologies, information is translated into electric pulses connected with varying amplitude. Inside digital technologies, translation connected with information is into binary structure (zero or one) where by each tad is agent of a pair of distinct amplitudes.

Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
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.
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
What are the differences between analog and digital transistors?
transducer convert one energy to other energy .now in analog transducer it convert energy use of analog signal and digital it converts use og digital signal
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 difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
What is difference between vga and lcd display?
The main difference between the tow is the signal. VGA uses an analog signal and DVI is a digital signal.
Difference between analog and digital signal processing?
we can do analog signal processing also but it is very expensive as comparing with digital signal processing that's why we generally choose the digital signal processing.DSP allows programmable operations.But we cannot do in ASP.
Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
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.
Difference between analog communication and digital communication?
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.
The difference between Digital signal and analog signal?
I'm not sure if you are speaking of a specific instance.... However, a digital signal is a binary representation of the analog signal. The analog signal is constantly measured and the amplitude (voltage at the time of sample) of the analog signal is converted to a binary number at specific intervals (the frequency of the sample rate). The higher the frequency of the sample rate, the more accurate the representation of the analog signal.
What is the difference between analog and digital transmitter?
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
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
What is difference between ask and am?
The most fundamental difference, I would say, is that Amplitude Modulation (AM) is a kind of Analog Modulation Technique (the modulation is applied continuously in response to the analog information signal) where Amplitude Shift Keying is a type of Digital Modulation Technique ( an analog carrier signal is modulated by a discrete signal, digital modulation methods can be considered as digital-to-analog conversion, and the corresponding demodulation or detection as analog-to-digital conversion. The changes in the carrier signal are chosen from a finite number of M alternative symbols).
