# Review Normal difficulty. Many problems were originated form slides. # Problems 1. Explain the difference between linear phase filter and nonlinear phase filter in terms of group delay, signal shape, etc. 2. Do all-pass decomposition of this system into minimum phase and all pass phase. 3. Show this system into difference equation and sketch amplitude response. Explain where does this filter uses. (Notch filter) 4. Sketch transposed form signal flow diagram of 5. Explain the implement method of impulse invariance and bilinear transformation. And what is the pros and cons for each method? 6.(a). is . Make ideal low pass filter as in z domain. 6.(b). Rectangular window, … (I don’t remeber) 7. Write down DFT and IDFT formula with twiddle factor. 8. Draw FFT butterfly diagram. What is the calculating complexity of FFT? 9.(a). In this spectrogram, what is the real world frequency of continuous noise? () 9.(b). Show the edge enhancing impluse response in image processing.
