Multirate signal processing can reduce costs and improve performance in applications
ranging from laboratory instruments to cable modems, wireless systems, and consumer
entertainment products. This book offers the first systematic, clear, and intuitive
introduction to multirate signal processing for working engineers and system
designers.
The author uses extensive examples and figures to illuminate a wide range
of multirate techniques, from basic resampling to leading-edge cascade and multiple-stage
filter structures. Along the way, he draws on extensive research and consulting
experience to introduce processing itricksi shown to maximize performance and
efficiency.
Coverage includes:
- Effective sampling and resampling in time and frequency domains
- Relationships between IIR Filter specifications and filter length (taps)
- Window design and equal-ripple (Remez) design techniques
- Square-Root Nyquist and Half Band Filters, including new design enhancements
- Polyphase IIR Filters: up-sampling, down-sampling, and cascade up-down sampling
- Polyphase interpolators and filters that perform arbitrary sample rate change
- Dyadic Half Band Filters, including quadrature mirror and IIR Filters
- Polyphase Channelizers, including M-path modulators, demodulator channel
banks, simultaneous interpolation, and channel bank formation
- Comprehensive coverage of recursive all-pass filtersoa topic never before
covered in this detail
- Comparisons with traditional DSP design techniques
- Extensive applications coverage throughout
