What is the difference between digital signal discrete signal and continuous signal?
A discrete time signal which is not quantized can take any value in the given range (i.e. infinite options for the amplitude) where as a digital signal can take any value from a predefined finite set of amplitudes. The digital signal can take any value out of these N values only ( and not just any value).
What is difference between continuous and analog signal?
A continuous signal cannot be stored, or processed, in a computer since it would require infinite data. Analog signals must be discretized (digitized) to produce a finite set of numbers for computer use. When analog signals are brought into a computer, they must be made discrete (finite and countable).
What is the definition of a discrete signal?
A discrete signal or discrete-time signal is a time series consisting of a sequence of quantities. Unlike a continuous-time signal, a discrete-time signal is not a function of a continuous argument; however, it may have been obtained by sampling from a continuous-time signal.
What are analog and digital signals, and their differences?
An analog signal is a continuous signal whereas Digital signals are time separated signals.
What is better analog or digital?
Analog is real time. Digital is not. This means that Digital is better because it can do everything analog can and then some. If you want to edit, encode, buffer and reproduce the output/input signals at the approximate same time of analog or at a later time, you can do so with digital.
What are some examples of analog signals?
A good example of an analogue signal is the loud-speaker of a stereo system. When the volume is turned up the sound increases slowly and constantly. Examples of analogue systems include; Old radios, megaphones and the volume control on old telephone hand sets. This graph is typical of digital signals.
