Filter Design – Philips Upsampler Overview Filter design and implementation is an important aspect of signal processing. Historically, in DSP courses, considerable emphasis was put on the theory of design techniques for both IIR and FIR filters, as discussed in Chapter 7 of the text. These techniques are now fully incorporated in a variety of software packages such as M ATLAB . However it is important (perhaps even more so) to understand the different classes of filters typically used and some of the tradeoffs between them. We feel that the best way for you to sort through these is by carrying out some design and implementation through this project. The project Upsampler Filter Design contains an excellent introduction to the issues presented in this project. In the context of IIR filter design, we suggest that you read Sections 7.0 and 7.1 including Example 7.1. Also, read the examples in Section 7.3.1, but focus on what Butterworth and Chebyshev filters are rather than on the details of the bilinear transformation. For the discussion of FIR filter design, the suggested reading is Sections 7.5, 7.6, and 7.7 through 7.7.1. We will not be going into the details of the issues raised in Section 7.7.1, but we would recommend at least reading that section to get a sense of what some of those issues are. Specific suggested reading for this project is the M.Eng. thesis by Daniel Turek “Design of Efficient Digital Interpolation Filters for Integer Upsampling” June 2004. A PDF of the thesis is available at http://www.rle.mit.edu/dspg/documents/main.pdf .
