No because it has finite power therefore infinite energy => not an energy 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.
An amplifier will amplify a signal. For example, the antenna in a radio will receive an extremely weak signal; before it can be converted to a sound, it must be amplified (made stronger), by a factor of several million. Of course, since you can't produce energy out of nothing, an amplifier doesn't actually produce the energy for the strong version of the signal - it requires a power supply.
carrier signal- use for the purpose of conveying information. modulating signal- causes variations in some characteristics of carrier signal. modulated signal - carrier signal after altration in its characteristics is called modulated signal. example- if you want to see an object (suppose it is an modulating signal),you need light(light is carrier signal) and when light will reflect on object you will be able to see if (that is modulated signal)
correctional signal
A digital signal is actually a complex signal. Consider the horizontal part of a digital signal as a component with 0 frequency and the vertical part of the signal as the component of infinite frequency. Also, consider the change from the horizontal to vertical as all the frequencies. Then we can claim that a digital signal is complex signal with frequencies from 0 to infinite.A digital signal is a composite analog signal with an infinite bandwidth.
In mathematics and engineering, the sinc function, denoted by sinc(x), has two slightly different definitions.[1]In mathematics, the historical unnormalized sinc functionis defined byIn digital signal processing and information theory, the normalized sinc function is commonly defined by The normalized sinc (blue) and unnormalized sinc function (red) shown on the same scale.
Sinc function is a cosine cardinal function
they have an infinite energy
a = a/2*b*sinC Multiply both sides of the equation by 2 to eradicate the fraction: 2*a = a*b*sinC Divide both sides by a*b which will enable you to cancel out "a" and also make sinC the subject: sinC = 2/b
a signal can never be both energy & power signal because they are mutually exclusive
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..
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.
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.
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).

Sinc - In mathematics, the sinc function, denoted by sinc(x) and sometimes as Sa(x), has two definitions. In digital signal processing and information theory, the normalized sinc function is commonly defined bysinc - A site generally identified by the local authority which warrants special protection because of its local importance for flora or fauna.sinc - areas of land and wetland of local importance for the conservation of semi-natural habitats including mosaics of heathland, unimproved grassland, scrubland and plantation and/or habitats which support rare local wildlife species. ...sinc - 1977 (non-fiction)sincs - Sites which are of particular value for wildlife in a county context and identified according to criteria agreed between Hampshire County Council, English Nature and Hampshire Wildlife Trust.
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.
