Ø Signal: a function of one or more variables that convey
information on the nature of a physical  phenomenon.
Examples: v(t),i(t),x(t),heartbeat, blood pressure,
temperature, vibration.
 One-dimensional signals: function depends on a single
variable, e.g., speech signal
 Multi-dimensional signals: function depends on two or
more variables, e.g., image
