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.
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
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).
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
How do you calculate Signal to Noise ratio?
It can be calculated by simplifying the ratio between power of signal by power of noise
Why random signals are called power signals?
Energy signals are finite duration. That means if a random signal is energy type, all its realizations or its sample functions must be zero at infinity. So its expected value or mean is zero at infinity. On the other hand, a stationary process has a time invariant mean. So if its expected value is zero in infinity, it will be zero in any time. In summary if a stationary random signal is energy, its expected value must be zero every time. But It is not correct for all signals. So it is not energy type.
Why any signal with finite energy will have zero power?
in energy signal power iz zero according to this equation P=E/2T
How you can determine whether signal is power signal or energy signal?
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.
Is impulse function is an energy signal or a power signal or both Explain?
it can not be both!
