A signal x(t) is called an energy signal , if the energy is finite and the power is zero.
A signal x(t) is called an power signal , if the power is finite and the energy is infinite.

∙ 13y agousuall, all time limited, non periodic signals are energy signals and all periodic signals are power signals... but there could be some exceptions... it is a power signal.......
This can be found out as below:
integrating square of 1 from 0 to T/2 will give -----> T/2 {as unit step exist frm 0 to inf}
Then, acc to the expression of power it will be divided by T
This will give: 1/2
as power..

Is ramp signal energy or power signal?
no...it is neither energy nor power signal . Rampis neither energy nor power signalbecause it has infinite energy as well as infinite power.....saket kumar (electronics & communication engineer),BMSCE MUKTSAR (PUNJAB).
Why any signal with finite energy will have zero power?
in energy signal power iz zero according to this equation P=E/2T
Is unit impulse an energy signal or power signal?
checking if it is an energy signal E= integration from 0 to infinity of t gives infinity so it is not an energy signal P=limit ( t tending to infinity)*(1/t)*(integration from 0 to t/2 of t) gives us infinity so it is not an energy or a power signal
Where does the energy come from to amplify the signal in a amplifier?
The energy comes from an additional power source, like a battery. Via various resistors and capacitors, the energy from the power source is put into the circuit. The signal that enters the ciruit will exit the circuit with a higher energy; the signal has been amplified.
Why do you use energy signal in real life although power of the energy signal is zero?
see p=E/t whr E is energy of a sig and t is time, if p iz zero it means t=0 and energy iz infinite means we can use max energy of a signal to travel it long distance,,,,,and it is possible only when power iz zero........
What is power signal and what is energy signal?
Those signals which have finite energy and zero power known as energy signal..Those signals which have infinite energy and finite power known as power signal..
Can a power signal be an energy signal?
a signal can never be both energy & power signal because they are mutually exclusive
Is ramp signal energy or power signal?
no...it is neither energy nor power signal . Rampis neither energy nor power signalbecause it has infinite energy as well as infinite power.....saket kumar (electronics & communication engineer),BMSCE MUKTSAR (PUNJAB).
Unit step signal is energy or power signal?
The unit step signal is a Power signal. Since when we find the power it comes to 1/2 (i.e finite value). And when we find its energy, we got INFINITY. If a signal has energy as infinity and power as a finite non-zero value, then it is a power signal, not an energy signal.
Is exponential signal an energy signal or power signal?
If the signal is not bounded by a step function, then an exponential signal is neither a power nor an energy signal. So the answer is neither.
Is sinc signal an energy signal?
No because it has finite power therefore infinite energy => not an energy signal
Why any signal with finite energy will have zero power?
in energy signal power iz zero according to this equation P=E/2T
Is impulse function is an energy signal or a power signal or both Explain?
it can not be both!
Is unit impulse an energy signal or power signal?
checking if it is an energy signal E= integration from 0 to infinity of t gives infinity so it is not an energy signal P=limit ( t tending to infinity)*(1/t)*(integration from 0 to t/2 of t) gives us infinity so it is not an energy or a power signal
How the energy and power of the random signal can be calculated?
i dont no

Define energy and power signal?
Here Energy signals are limited but power signals can exist to infinite distance. Non periodic signals are energy signals while power signals are periodic.
