Definition: For a function f(t) (f(t)=0 for t<0),
f(t) (f(t)=0 Design specs
Frequency domain (s: complex variable) f(t)
f(t) PID & Lead-lag
LeadDesign examples 0 t F(s)
F(s) We denote Laplace transform of f(t) by F(s).

equation into an algebraic equation which is
easy to solve. (Next lecture)
It is easy to analyze and design interconnected
(series, feedback etc.) systems. (Throughout the
Frequency domain information of signals can be
