EEL3135 Fall 2011 Quiz 5 BJ Trivedi , Christopher Wilson and Mayank Devam Name:__________________________ _____ ______________________ UFID:________________ Quiz A Score: _____/10 Consider the following signal . In order to compute the 3-pt DFT of the signal we apply the definition for k=0,1,2 where N=3. Calculate the DFT Coefficients as specified below. 1. (2pt) Calculate the Coefficient X[0] 2. (2pt) Calculate the Coefficient X[1] 3. (2pt) Calculate the Coefficient X[2] 4. (2pt) Short Answer: The limits for summation in calculating the coefficients of the DFT are evaluated over N frequencies. Sometimes we will have a sequence x[n] with length L, where L < N. In such cases, what must be done to x[n] to carry out the computation? Pad the signal with N-L zeroes. 5. (2pt) Short Answer: What is the algorithm that can evaluate the DFT reducing the number of computations needed for N points from 2N 2 to ? FFT. Last First

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
