Q1. What do you mean by Laplace transform?

Ans.: The Laplace transform of a function f(t) in time domain t is given by

 

 

where                   s = σ + jω

 

The notation LT indicates “Laplace transform of.”

 

 

The Laplace transform can be applied to two-sided as well as one-sided functions. When applied to two-sided functions, it is termed as bilateral transform (BLT). Most of the engineering functions are one-sided functions i.e., these functions are zero before a particular instant of time (t = 0) and we ...
