Abstract
A discrete time signal is one that has a value only for a finite or infinite number of time instants whereas a continuous time signal has a value for every (real) time instant. For example, consider:
-
The sound pressure wave of a speech signal
-
The electrical that is the output of a transducer that is used to mesdsure the cound pressure wave of a speech signal
-
The sequence of numbers that is obtained from connecting an analg to digital converter (ADC) to the electrical signal sound pressure wave of a speech signal
