PPT-The Laplace Transform

Let fx be defined for 0xlt and let s denote an arbitrary real variable The Laplace transform of fx designated by either fx or Fs is for all values of s for which the improper integral converges. Like the Fourier transform a constant Q transform is a bank of 57356lters but in contrast to the former it has geometrically spaced center frequencies 0 where dictates the number of 57356lters per octave To make the 57356lter domains adjectant one 1 which is now called Heaviside step function This is a discon tinous function with a discon tinuity of 64257rst kind jump at 0 which is often used in the context of the analysis of electric signals Moreover it is important to stress that t he Havis Definition of Bilateral Laplace Transform.
