, ➢A signal is defined as a single-va
SIGNAL function of one or more independ
variables which contain s
information.
➢Represented in time domain
frequency domain.
Ex: Human Speech,
Electric Current and Volta
, ➢An entity that acts on an inpu
SYSTEM signal and transforms it into a
output signal.
➢It can determine the exact
relation between the input x
and the output y(n), and
specifies the output for every
input.
, SIGNAL PROCESSING
➢Extracting information from the signal.
➢Nature of information it carries.
➢Representing signals in the mathematical terms.
➢Extracting information by carrying out algorithmic operations
on the signal.
