Fourier Analysis

This unit will discuss the following topics based on Fourier series:

• Fourier Transform
• Convolution
• Some Common Functions
  • rect function
  • sinc function
  • $\delta$ function
  • comb function
• Sampling Theorem
• Discrete Fourier Transform
• Fast Fourier Transform
• DTMF Application

These can also be considered part of Fourier analysis, but in reality, the content and applications of Fourier analysis are much more extensive. Here, we only touch on a fraction of it.
