for more detail kindly read this
Energy Signal is a signal that has energy only in finite time not over all time .and as we know the power of a signal is the rate of its energy over the time .. that is the (energy/time).. So, in the energy signal (power = (finite)energy /(infinite)time [over all time]) that equals to ZERO

Power Signal is a signal that has a finite power (not equals to ZERO) .. and as we say above that the (power = energy/(infinite)time [over all time]) .So, the energy is very very big that tends to Infinity

This is example of energy signal (unit sample signal) .. Because it has energy only in period of time So its power is ZERO


This is example of power signal (unit step signal) .. Because it has infinite energy So its power is finite

i dont understand every one just goes on reading the formulas as it is... cant we read in textbook? ... noone is taking care of subject oriented classes or explanations.... pity on us.... what is there so special in ur video if everything is same as in teaching profession has so many ethics follow it... its teaching a topic means teaching the internal beauties of the concept explaining what it is.... not saying the formulas.... everyone knows it...

[vedurubhavanireddy]

Can you explain how a
power of energy signal =0
Energy of power signal=infinity

[amittak]

Tell these formula for discrete time signal also

[hammadullahasghar]

plz explain LTI system for continuous time signal

[vibeeshk]

@0.43 written in the box and explanation is wrong

[Excelchamp]

Plz make a video on how the total energy of a power signal is zero

[prabhakarch]

Impulse signal is energy signal or power signal

[kchithra]

What is the relation between energy and power signals

[aerodynamico]

You've totally screwed it up, ma'am. You are confused yourself; how can you teach others?
