View the content: IIR Coefficient Quantization Analysis

Metadata

Name: IIR Coefficient Quantization Analysis
ID: m11926
Language: English (en)
Summary: Proper coefficient quantization is essential for IIR filters. Sensitivity analysis shows that second-order cascade-form implementations have much lower sensitivity than higher-order direct-form or transpose-form structures. The normal form is even less sensitive, but requires more computation.
Subject: Science and Technology
