Q1. In a window-based 2D FIR filter design, the window order has the following effect on the filter design:

a. The higher the order, the more complex the designed filter
b. The smaller the order, the simpler it is to implement the filter
c. The higher the order, the better the quality of the filter
d. All of the above

  Q2. A 2D FIR filter is designed and implemented in a system. In what respect does the filter order affect the memory in that system?

  Q3. In a window-based 2D FIR filter design, which design gives a better circularly symmetric filter?

a. Separable
b.Non-separable
c. None of the above

  Q4. When designing a 2D FIR filter with sharp cut-offs, what is the compromise that has to be made?

  Q5. In a window-based 2D FIR filter design, which window provides fast filter implementation or less complexity?

a. Hamming
b. Kaiser
c. Rectangular
d. Hanning

  Q6. Which filter properties cannot be jointly optimized in a window-based 2D FIR filter design?

a. Better filter quality in pass- and stop-bands, and sharp cut-off
b. Lower side-lobes and better noise rejection
c. Better pass-band quality and better noise rejection
d. Sharp cut-off frequency and lower side-lobes

  Q7. 7) A low-pass 2D FIR filter is designed using a non-separable rectangular window of order 7 with cut-off frequency of 0.4PI. If the same exact filter is designed using a Kaiser window, what should the design specifications be in order to get the same frequency response?

  Q8. What type of window is preferred in the design of a window-based 2D FIR filter to ensure better frequency selectivity?

a. Hamming
b. Kaiser
c. Rectangular
d. Hanning
