@NaqashHaider You find the energy of a discrete signal by summing rather than integrating. Square each signal value and then sum them to find the signal energy.
@teene0 The power spectral density is a function of frequency that shows how much power is at each frequency. The power in this lecture can be obtained by integrating the power spectral density over all frequencies.
Thank you for sharing your knowledge :-)

How i am gonna find the energy of discrete signal.......
can i still use integration?????
can any1 answer this dumb question?????

Thank you for the nice lecture. I am just wondering if the power in this lecture and Power spectral density/Power spectra are the same thing?
