Lab 5: The Fast Fourier Transform (FFT)

Q1. The contents of this exercise helped you understand the general concepts of using Fast Fourier transform in signal analysis.

Q2. Which part of the exercise helped you the most to understand how and when to use the FFT?

Q3. The exercise helped you to clearly visualize signal symmetries on the FFT spectra.

Q4. This lab strengthened your perception about various window trade-offs.

Q5. By performing this exercise, you understand that spectral resolution of the FFT is limited by frame size, window type and window size.

Q6. Did you experience any problems in terms of connection, time to implement etc? Please describe.

Q7. Was there enough information in the help screens to assist you in using the blocks?

Q8. Is there any particular concept, which you could not grasp earlier from your text book/class, but became clear from this exercise? If so, please describe.

Q9. Performing the exercises, you are now more comfortable with these topics.

Q10. Setting up the required lab simulations was pretty easy.

Q11. Can you suggest an exercise along the lines of this one?

Q12. Please suggest possible improvements relative to this lab (such as redesigning of dialog box of a block - what to add or delete etc).
