1. Various comparisons are stated in the text and the lecture material between Butterworth and Chebyshev Type I IIR filters. What sort of criteria do you think should be used in deciding which type of filter to use?

2. Coefficient quantization has been demonstrated to have a significant effect on the processing of digital IIR filters. How do you think the introduction of feedback terms in IIR filters is affected by quantization, and is it more or less critical than the effect upon FIR filters? Include in your answer any differences or comparisons you have noticed between the aky[n-k] filter coefficients and the bkx[n-k] filter coefficients.

3. What is the difference between a single-phase and a three-phase ac signal?
