Can you use an amplifier circuit to convert sound energy into electrical energy?
No. Power can't be amplified, because to do so would require the creation ofenergy, which is always a no-no. However, a circuit with small power can beused to control a circuit with large power derived from somewhere else. Soif you can maintain sufficient power-input to the high side, the whole operationhas the appearance of having amplified the low power. The best example of thatprocess is any radio receiver.
What is the energy transformation of a traffic light?
A traffic light typically uses electrical energy to power its light bulbs, which convert the electrical energy into light energy. The light energy is then used to signal drivers on the road.
Define power in physics?
In physics, power is the rate at which work is done or energy is transferred. It is defined as the amount of energy transferred or converted per unit time. The SI unit of power is the watt (W), which is equal to one joule per second.
What is spectral energy density?
The energy spectral density describes how the energy (or variance) of a signal or a time series is distributed with frequency.You can read more in Wikipedia 'Spectral Density', but you will need good maths to understand it!
What is the energy transformation that takes place in a television?
Simple answer: Electrical energy comes in and heat, light and sound energy goes out. There are two input sources, the electromagnetic signal that is the actual information of what is to be displayed and there is also the electric power provided to operate the television. Typically, the power comes from an electrical cord plugged into the electrical outlet on the wall and the signal is a cable from an outside source or an antenna. The input energy is electrical energy to power the TV and the signal is electromagnetic energy. The output of primary interest is the image on the screen which is light energy, so the television puts out light energy which is also electromagnetic energy. The television may also produce sound, in which case there is sound energy put out. In the process of making light and sound, the components of the television heat, so heat energy is put out. Summary: Input: Electrical energy enters in two forms, electromagnetic signal and electricity. The electricity is the far greater source of energy. The energy in the signal is tiny. Output: Heat, light and sound exit the television. Heat is the largest and in excess of 90%. Sound energy will be substantially greater than the amount of energy contained in the light.
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
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.
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!
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
