Energy and power signal

[giritharan10]

The Energy and power signal can be related by,

P=lim(t->infinity) E/2T

Now consider x(t) is a power signal.
Then its energy value is infinite.
Thus when we substitute the energy value to the above equation, the Power value also becomes infinite.

This case is applicable to all the power signals.

How is this possible..?
Is my analogy right???
or am I doing any mistake???
Plz. help me.....

in lim(t->infinity) (E/2T), if E is infinite, then after applying limits the T value also becomes infinity. then the final result will be

=infinity/2(infinity)= some finite value
so for power signal, power is finite and energy is infinite

Mr.dillikumar406,

Infinity/Infinity= One of the indeterminate form........ Thus it is impossible............

here both of them doesnot leads to infinity, its just an assumption of having a maximum value.
