- 5.5 POLYNOMIAL APPROACHThe previous section showed how to iterate a difference equation in order to determinethe output sequence. It is particularly important to understand the relationshipbetween difference equations and their transforms. The z transform of a linear systemgives us the key to combining systems together to form more complex systems, sincethe z transforms in combined blocks are able to be multiplied or added together asnecessary. We now give another insight into this approach.Supp -- 5.6 POLES, ZEROS, AND STABILITY -- 5.7 TRANSFER FUNCTIONS AND FREQUENCY RESPONSE -- 5.8 VECTOR INTERPRETATION OF FREQUENCY RESPONSE -- 5.9 CONVOLUTION -- 5.10 CHAPTER SUMMARY -- CHAPTER 6: TEMPORAL AND SPATIAL SIGNAL PROCESSING -- 6.1 CHAPTER OBJECTIVES -- 6.2 INTRODUCTION -- 6.3 CORRELATION -- 6.4 LINEAR PREDICTION -- 6.5 NOISE ESTIMATION AND OPTIMAL FILTERING -- 6.6 TOMOGRAPHY -- 6.7 CHAPTER SUMMARY -- CHAPTER 7: FREQUENCY ANALYSIS OF SIGNALS -- 7.1 CHAPTER OBJECTIVES -- 7.2 INTRODUCTION -- 7.3 FOURIER SERIES -- 7.4 HOW DO THE FOURIER SERIES COEFFICIENT EQUATIONS COME ABOUT? -- 7.5 PHASE-SHIFTED WAVEFORMS -- 7.6 THE FOURIER TRANSFORM -- 7.7 ALIASING IN DISCRETE-TIME SAMPLING -- 7.8 THE FFT AS A SAMPLE INTERPOLATOR -- 7.9 SAMPLING A SIGNAL OVER A FINITE TIME WINDOW -- 7.10 TIME-FREQUENCY DISTRIBUTIONS -- 7.11 BUFFERING AND WINDOWING -- 7.12 THE FFT -- 7.13 THE DCT -- 7.14 CHAPTER SUMMARY -- CHAPTER 8: DISCRETE-TIME FILTERS -- 8.1 CHAPTER OBJECTIVES -- 8.2 INTRODUCTION -- 8.3 WHAT DO WE MEAN BY "FILTERING"? -- 8.4 FILTER SPECIFICATION, DESIGN, AND IMPLEMENTATION -- 8.5 FILTER RESPONSES -- 8.6 NONRECURSIVE FILTER DESIGN -- 8.7 IDEAL RECONSTRUCTION FILTER -- 8.8 FILTERS WITH LINEAR PHASE -- 8.9 FAST ALGORITHMS FOR FILTERING, CONVOLUTION, AND CORRELATION -- 8.10 CHAPTER SUMMARY -- CHAPTER 9: RECURSIVE FILTERS -- 9.1 CHAPTER OBJECTIVES -- 9.2 INTRODUCTION
