pulsed is like a beating heart while digital is your face
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
The main difference between the tow is the signal. VGA uses an analog signal and DVI is a digital signal.
A: square wave can be positive and or negative. A digital signal is a square wave but it can be of invariable duty cycles
discrete signal varies on the independent variable scale (example time scale) digital signal varies on the dependent variable scale as well
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.
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
Digital phone service uses exisiting phone lines. VOIP service uses your internet signal.
The way in which the information is encoded is the difference between a digital and an analog television signal. Traditional television signals are prone to fading, ghost images, and static. A digital television signal produces a crystal-clear picture and sound without fading or interference.
hi, actually non-continuous signals is one of a characteristics which define a Digital Signal.#non-continuous means having a finite or countably infinite number of values, which is exactly a defining property of a digital signal. therefor its not right (wrong) to ask the difference between the two.hope it help. :)
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.
Analog signals are continuous while digital signals are discrete
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).
