Topic 1: Fourier transform as a function of frequency ω versus Fourier transform as a function of frequency f (in hertz).

• • Text slecture by Dauren
  • Text slecture by Randall Cochran
• Topic 2: Definition of the "rep" and "comb" operators. (Note that there are two ways to define each of these operators: using multiplication/convolution with an impulse train, or using a summation formula without impulse-train. You should include both representations and explain how to go from one to the other.) DEADLINE September 19
  • Text slecture by Xiaozhe Fan
• Topic 3: Fourier transform of "rep" and "comb". (Make sure to carefully explain how to compute the Fourier transform of an impulse-train. You do not need to prove the multiplication/convolution property of the CTFT, but state it clearly whenever you need to use it.) DEADLINE October 1
  • [[|Video slecture by Ben Capano
  • slecture by Youqin Liu
  • Text Slecture by Matt Miller
• Topic 4: Discrete-time Fourier transform (DTFT): definition, periodicity property, example (computation of DTFT of a complex exponential- no fudging!) DEADLINE October 1
  • Text Slecture by Jacob Holtman
  • Text Slecture by Fabian Faes
  • Text slecture by Xian Zhang
• Topic 5: Discrete-time Fourier transform (DTFT) of a sampled cosine. (Include Case 1) sampling rate above Nyquist rate, and Case 2) sampling rate below Nyquist rate.) DEADLINE October 3

  • Frequency Downsampling by John Sterrett
  • Text slecture by Yerkebulan
  • Text Slecture by David Klouda
