Salutations,
I am attempting to find the signal energy for a waveform. I know
that signal energy is calculated by squaring the signal and then
integrating over the bounds of the signal. I have not found a
good vi from labview that properly performs this task. I have
looked at integral x(t).vi, integral x(t) ptbypt.vi. Both of
these functions seem to prove inaccurate; I attempted to integrate the
numbers 0,1,2,3,4,5,6 (t ->.5t^2) with a sample dt of 1. This
should have returned a value of 18, but I did not obtain this number.
Is there some mistake I am making in the labview idea, or is there a
better VI that will calculate the signal energy. I have looked at the
STFT approach; however, this seems to be a rather robust technique for
just finding a simple integration value.
Sincerely,
E. Smith
