In order for a signal to be detected, it must impart energy to the receiver, so, no, there are no signals that have no energy. It might seem that there is no energy. If you carefully consider capacitive and inductive reactance, however, you will note that current and voltage can be out of phase. If they are 90 degrees out of phase, then a "normal" meter will show no power, but there is energy transfer in any case.
What else can I help you with?
Why any signal with finite energy will have zero power?
in energy signal power iz zero according to this equation P=E/2T
Is sinc signal an energy signal?
No because it has finite power therefore infinite energy => not an energy signal
Is sinusoidal signal be an energy signal?
they have an infinite energy
Can a power signal be an energy signal?
a signal can never be both energy & power signal because they are mutually exclusive
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..
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.
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 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).
What is the signum signal are power or energy signal?
The signum signal, defined as ( x(t) = \text{sgn}(t) ), is an example of a power signal rather than an energy signal. This is because it does not have finite energy; its integral over all time diverges. However, its average power can be calculated and is finite, which classifies it as a power signal. In summary, the signum signal is a power signal due to its infinite energy and finite average power.
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
What type of energy transformation does a radio signal have?
The radio signal itself, of course, is not an energy transformation - energy transformation means that energy is changed from one type to another. There is an energy transformation when the radio signal is created, and another one when it is absorbed.
Is impulse function is an energy signal or a power signal or both Explain?
it can not be both!
