What is a discrete signal?
A discrete-time signal is a sequence of values that correspond to particular instants in time. The time instants at which the signal is defined are the signal's sample times, and the associated signal values are the signal's samples.
What is difference between digital and discrete signal?
Digital signal - signal is continuous in time but discrete in amplitude. Discrete in amplitude means signal cannot have multiple amplitude values . It can be a 1 or 0 . Discrete signal - signal is discrete In time but continuos in amplitude .
What is difference between continuous and discrete signal?
A signal, of which a sinusoid is only one example, is a sequence of numbers. A continuous-time signal is an infinite and uncountable set of numbers, as are the possible values each number can have.
What are examples of discrete signals?
Discrete-time signal: the variable of time is discrete. The weekly Dow Jones stock market index is an example of discrete-time signal.
