| Sep 8, 2014 at 12:28 | comment | added | Matt L. | @user94533: You mean a periodic ramp (sawtooth)? For periodic signals the power is $P_x=\frac{1}{N}\sum_{n=0}^{N-1}|x_n|^2$, where $N$ is the period. | |
| Sep 8, 2014 at 12:25 | comment | added | suhail | i meant for a signal like sin(t) which runs from -inf to inf .how do i calculate the power.also in case of a ramp function how do i do it using matlab.those are not finite length cases | |
| Sep 8, 2014 at 12:21 | comment | added | Matt L. | @user94533: As I said in my answer, for finite length signals, the power is zero. | |
| Sep 8, 2014 at 12:20 | comment | added | suhail | could u help me in implementing the power equation in matlab.I can do the energy part but could not make out how to calculate the power | |
