Determine the Laplace transform, F(s), of the following time signal. Solution we\'ll be interested in signals de¯ned for t ¸ 0 the Laplace transform of a signal (function) f is the function F = L(f) de¯ned by F(s) = Z 1 0 f(t)e¡st dt for those s 2 C for which the integral makes sense ² F is a complex-valued function of complex numbers ² s is called the (complex) frequency variable, with units sec¡1; t is called the time variable (in sec); st is unitless ² for now, we assume f contains no impulses at t = 0 common notation convention: lower case letter denotes signal; capital letter denotes its Laplace transform, e.g., U denotes L(u), Vin denotes L(vin), etc..
