In this chapter we begin the use of transformations for the representation and analysis of continuous-time signals and systems. The Laplace transform is obtained when applying complex exponentials or eigenfunctions to linear time-invariant (LTI) systems. Together with a region of convergence in the ...

The Laplace transform is a mathematical tool which converts the differential equations in time domain into algebraic equations in the frequency domain (or s-domain).If x(t)x(t) is a time function, then the Laplace transform of the function is defined as −L[x(t)]=X(s)=∫∞−∞x...

Equation (1) gives the bilateral Laplace transform of the function x(t)x(t) . But for the causal signals, the unilateral Laplace transform is applied, which is defined as,L[x(t)]=X(s)=∫∞0x(t)e−stdt⋅⋅⋅(2)L[x(t)]=X(s)=∫0∞x(t)e−stdt⋅⋅⋅(2)...

In addition, there are also several lookup tables for the Laplace transforms of common functions available, to help along the way. We will thus get the response of the circuit in the frequency domain. Thereafter, if so desired, we can use the “inverse Laplace transform” to recover the ...
