1.11 Applications of Fourier Series and Integrals

• You can use a change of variable.

• The most basic tools of applied mathematics are the Fourier series and integrals.
• There are a few applications that do not fall within the scope of the rest of the book.

• A large response can be caused by a small denominator.

• The sampling theorem is one of the most important results of information theory.

• There is an easy way to find the Fourier transform of a function.

• By using Eq.

• This is the main result.

• It is difficult to determine what functions are limited.
• The process usually works well.

• 2 can be approximated from a finite portion of the sum.
• The function is not functioning.

• There are graphs of approximation using sampling.

• There are other ways to solve the differential equation.
