Guest Editorial: Low-Power Digital Filter Design Techniques and Their Applications

摘要

Welcome to this Special Issue on Low-Power Digital Filter Design Techniques and Their Applications. Digital filters are essential elements of many signal processing systems and everyday electronics such as radios, cell phones, and biomedical devices. With the ever-increasing popularity of portable devices in communication, medical, and audio/video systems, the computational efficiency and power consumption of digital filters have become increasingly a matter of concern, as digital filters usually involve a large number of arithmetic operations, especially for the finite impulse response (FIR) filters.
