Comprehensive introduction to analysis of continuous and discrete-time signals and systems. Linear time-invariant systems, convolution; Fourier series representations of periodic signals; Continuous ...

Harmonic univalent mappings are complex functions defined on the open unit disk that satisfy Laplace’s equation and exhibit a one-to-one correspondence between the domain and their image. These ...

In this paper three methods are derived for approximating $f$, given its Laplace transform $g$ on $(0, \infty)$, i.e., $\int^\infty_0 f(t) \exp(-st) dt = g(s ...

While analyzing any system we generally do it in 2 domains time and frequency domain because both of them give us different perspective and a better insight into the system. Time domain looks suitable ...

Advances in Applied Probability, Vol. 19, No. 3 (Sep., 1987), pp. 632-651 (20 pages) We consider a class of functions on [0,∞), denoted by Ω , having Laplace transforms with only negative zeros and ...
