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
discrete fourier transformer uses digital signals whereas the fast fourier transform uses both analog and digital.
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.
The words discrete and discreet are pronounced in the same way and share the same origin but they do not mean the same thing. Discrete means 'separate,' as in a finite number of discrete categories, while discreet means 'careful and circumspect,' as in you can rely on him to be discreet .
A discrete random variable (RV) can only take a selected number of values whereas a continuous rv can take infinitely many.
Fourier series is the sum of sinusoids representing the given function which has to be analysed whereas discrete fourier transform is a function which we get when summation is done.
Analog signals are continuous while digital signals are discrete
discrete signal varies on the independent variable scale (example time scale) digital signal varies on the dependent variable scale as well
discrete fourier transformer uses digital signals whereas the fast fourier transform uses both analog and digital.
The difference between continuous and discrete system lies in the variables. Whereas the continuous systems have dynamic variables, the discrete system have static variables.

An analog representation displays information in a continuous way, for example... the presentation of a wall clock shows the time in as a continuous variable, taking on any value within its constituent resolution. digital representation, also called discrete representation, displays information in terms of discrete, symbolic values, normally in terms of codes. In keeping with the same example, a digital representation would be a digital clock, whose representation of time is in terms of discrete variables (numbers)
The difference between the analog mul-titester and a digital mul-titester is that an analoq mul-titester varies in continues scale while the digital mul-titester has discrete values that is zero (0) and one (1).

A simple continuous distribution can take any value between two other values whereas a discrete distribution cannot.
