<P>I would suggest to rephrase the first sentence as "of a real signal x(t)".</P>
<P>I don't really understand the mathematical meaning of the sentence "The discrete version of the Laplace transform of a discretely and evenly-sampled signal is <U>a generation</U> of the above continuous version", but that is probably because "generalization" is meant instead.

<P>The LV 2012 help for the Real Laplace Transform.vi is erroneous.</P>
<P>Her is what it says:</P>

<P>Basically, it shows the FFFT definition twice. The correct redaction is available online (for instance, see <STRONG><A href="http://zone.ni.com/reference/en-XX/help/371361E-01/lvanls/laplace_transform_real/" target="_self">here</A></STRONG>).</P>Thu, 30 Aug 2012 20:57:56 GMThttps://forums.ni.com/t5/LabVIEW/Real-Laplace-Transform-Help-Typo/m-p/2141936#M692872X.2012-08-30T20:57:56ZRe: Real Laplace Transform Help Typo
