Test 2 Preparation

Material posted to assist your studying:

• Homework 3 Solutions.
• Homework 4 Solutions.
• Homework 5 Solutions.
• Review guide - part 1 (does not include filter design, DFT, DCT).
• Old example test (does not include DFT, DCT).

Review guide - part 2 - additional key review ideas:

• Unit notes are posted under the resources page.
• Be able to calculate circular convolution. See 8.6.5 and particularly examples 8.10, 8.11.
• Be able to calculate linear convolution using the DFT. See 8.7 and example 8.12 relative to time aliasing.
• Be able to implement LTI systems using the DFT and block convolution (overlap-add and overlap-save). See 8.7.3.
• Understand the relationship between the DFT and DCT-2. See 8.8.4.
• Understand energy-compaction in the DCT-2. See example 8.13.
• Example problems for chapter 8 with solutions: 8.11, 8.14, 8.17, 8.28.
