It marks them sure in the dominion of the time
1) Spazio works them:
E' constituted from with of marks them for which it exists
and it is ended the norm p_esima 
.
For p = 1 it is spoken about marks them absolutely integrabili while for p = 2 it is spoken about marks them quadratic integrabili.
2) instantaneous Power of marks them:
It is the module picture of marks them that is same |x(t)|2 .
3) Energy of marks them:
The energy is the integral of the instantaneous power 
.
4) It marks them of energy:
They are marks them for which andxx assumes one ended value, their space works them is L2 they can be is limits you that illimita to you in the time, in this case characterizes a practical duration T to the outside of which it is assumed that it marks is worth them zero. All it marks them prati are marks them of energy in how much have limited duration.
5) medium Power of marks them:
In the case it marks them s(t) is limitless in the time
and it does not have ended energy, considers the temporal medium power
of marks them 
essendo
marks cut them.
6) It marks them of power:
It is marks them for which the medium power assumes an ended value.
7) medium Valor of marks them:
, it is various from 0 solos for marks them of power.
8) Member alternated of marks them x(t):
9) Factor of peak:
It is reported to marks them symmetrical, which are
lacking in continuous member and have opposite value the maximum and
minimal value,
is had: 
10) Function of retort:
if the period T 0is only greater of the T periody of it marks them source obtains a course similar to it.
11) Power of marks them periodic obtained for repetition of marks them of ended duration:
being andxx0 the energy calculated to the inside of a period, it coincides with andsingle YY if TY < T0 .
12) Energy for sequences:
the energy is estimated therefore of marks them continuous obtained from that discreet one by means of the operation of âtenutaâ?, moreover for convention assumes T = 1.
13) Power for sequences:
the power is estimated therefore of marks them continuous obtained from that discreet one by means of the operation of âtenutaâ?, moreover for convention assumes T = 1.
14) Function of temporal intercorrelationship or temporal mutual correlation:
characterizes the degree of likeness between 2 
funzioni.
Attention to the fact must be placed that does not coincide with the convoluzione product.
15) mutual Energies:
Draft of the function of intercorrelationship calculated in t = 0 
.
16) Function of index of temporal intercorrelationship :
It is the relationship between the intercorrelationship
function and the root of the product of the energies 
turns out moreover |rxy(t)| £ 1.
17) Function of autocorrelationship of marks them of energy:
draft that is of a hermitiana function with real value in origin Cxx(0) = andxx , measure the affinity between marks them traslato in the time regarding what not trasla.
18) Product to climb of 2 marks them:
Draft of the value in the origin of the function of
intercorrelationship between two marks them 
,
measure the affinity of the two marks not traslati them.
19) It marks them parallels, antipodali, orthogonal:
Currency the index of intercorrelationship 
is had:
to) rxy = 1 it marks them parallels
b) rxy = 0 marks them orthogonal
c) rxy = -1 marks them antipodali
20) Function of intercorrelationship of marks them of power:
21) mutual Powers:
Draft of the values assumed in the origin from the functions of intercorrelationship Pxy = Rxy(0) = R*yx(0) = P*yx .
22) Function of index of temporal intercorrelationship of marks them of power:
It is an adimensional function defined 
, its module is always smaller of 1.
23) Function of temporal covarianza for marks them of power:
It is the function of temporal intercorrelationship of the members to valor medium null:
24) Function of temporal autocorrelationship of marks them of power:
Hermitiana function characterizes the affinity of marks
them traslato in the time with that one 
traslato
is not therefore one.
25) Function of temporal autocovarianza:
26) Family of marks incorrelati them:
A family of marks them says incorrelata if all the covarianza functions are null Kxy(t)=0.
27) Family of marks them incoherent:
She is of with of marks them of power for which for every t the functions of intercorrelationship C xy (t)=0arenull all.
28) Sequences of intercorrelationship between sequences to ended energy:
29) temporal Sequences of autocorrelationship for sequences to ended energy:
it from a measure of the speed of variation of marks them same.
30) temporal Sequences of autocorrelationship for sequences to ended power:
31) Sequences of autocovarianza:
