Reading Assignment Due Monday, 10/31:
Read pp. 397 – 419 in the Roads, and answer the questions below.
1. What is the unit impulse?
2. What is the relationship between a filter’s frequency response and its impulse response (IR)? How do they differ?
3. Give the intuitive measurement for phase response.
4. What is the basic mathematical procedure for a simple lowpass filter?
5. What is the basic mathematical procedure for a simple highpass filter?
6. What effect on the filter is produced by adding more samples to the delay line? (both in terms of frequency response and phase response)
7. Discuss the general difference between a finite impulse response (FIR) filter, and an infinite impulse response (IIR) filter. (this difference comes both from the basic equations, and from the advantages/disadvantages section)
