Topic:-
Signals & its Types

Def:
Signal is a function of measure, distance, position, temperature & it represents some variable of interest associated with the system.

Types of Signal:
Continuous snip heads.
Discrete season signals.
Both continuous and separate term signals are hike up classified into:-
deterministic signals.
Non settled signals.
Periodic & A biyearly signals.
Even & spotty signals.
Energy & Power signals.


Continuous time signals:
A continuous-time real (or complex) signal is any real- look upond (or complex-valued) function which is outlined for all time t in an interval, most commonly an infinite interval.


Discrete time signals:
It is specified only at certain time distance .The amplitude of a discrete time signal b/w two time instances is just not specified.







Deterministic signals:
Deterministic signals are those signals whose determine are completely specified for any given time. Thus, a deterministic signal can be modeled by a known function of time I .






Deterministic signal for continuous time

Deterministic signal for discrete time

Non Deterministic signals:
Random signals are also called non deterministic signals are those signals that clear random values at any given time and must be characterized statistically.


Periodic & A biyearly signals:
A continuous-time signal x ( t ) is said to be periodic with period T if there is a positive nonzero value of T for which
x(t + T ) = x ( t )
x(n+N0)=x(n)
A signal which does not satisfy above equations is called a periodic

Even & Odd signals:
signal x ( t ) or x[n] is referred to as an yet signal if

x ( - t ) = x (t )
x [ - n ] = x [ n ]
A signal x ( t ) or x[n] is referred to as an odd signal if
x ( - t ) = - x ( t )
x [ - n ] = - x [ n ]

Even signal for continuous time.
