What is periodicity of unit step signal?
YES, unit step function is periodic because its power is finite that is 1/2.. and having infinite energy.
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.
What is the Measurement of power energy power factor?
Power - Watt. Energy - Watt Hour. Power factor - no unit. just number less than or equal to 1.
What is power spectral density?
power spectral density (PSD), which describes how the power of a signal or time series is distributed with frequency. Here power can be the actual physical power, or more often, for convenience with abstract signals, can be defined as the squared value of the signal, that is, as the actual power if the signal was a voltage applied to a 1-ohm load.Since a signal with nonzero average power is not square integrable, the Fourier transforms do not exist in this case. Fortunately, the Wiener-Khinchin theorem provides a simple alternative. The PSD is the Fourier transform of the autocorrelation function, R(Ï„), of the signal if the signal can be treated as a wide-sense stationary random process.The power of the signal in a given frequency band can be calculated by integrating over positive and negative frequencies.The power spectral density of a signal exists if and only if the signal is a wide-sense stationary process. If the signal is not stationary, then the autocorrelation function must be a function of two variables, so no PSD exists, but similar techniques may be used to estimate a time-varying spectral density.

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.
What is periodicity of unit step signal?

What is spectral density per unit bandwidth?
it states the power and energy of a given signal in terms of frequency
What is unit impulse function?
the unit impulse function g(t)
A unit of energy is the unit of what?
... is called power. The SI unit for energy is the joule; the SI unit for power is joule/second = watt.
Is a calorie energy or power?
It is a unit of energy
Is a watt a unit of power or a unit of electrical energy?
Watt is a unit of power. 1 Watt = 1 Joule/second; joule is the unit for energy.
Why you take energy bill in units of energy instead unit of power?
Energy bill must be in terms of Energy unit (KWH) only. Energy is KW (power) utilized over a period of time. The unit of energy is Kilowatthour (KWH) Unit of power is Kilowatt (KW) KW is instantaneous power being utilized. KW (power) over a time period is Energy (KW H)
Is watt a unit of energy?
Joule is a unit of energyWatt is a unit of power
Is kWh a unit of power or a unit of work explain.?
It is a unit of work or energy. Watts are a unit of power or energy per second. Watts times seconds is energy, thus the 'h' hours of kWh is what turns power to energy.
How much is one Watt of energy?
A watt is a unit of power, not of energy. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.A watt is a unit of power, not of energy.
