Once a filter is designed, it must be implemented. The book illustrates various realization structures: Direct Form I and Direct Form II. Cascade and Parallel forms. Lattice structures for FIR and IIR filters. 8. Finite Word-Length Effects
After reviewing the solved examples, attempt the exercises at the end of each chapter without looking at the solutions. This builds exam-room confidence.
