Biologically inspired auditory sensing system interfaces on a chip
SENSORS, 2002 IEEE - Tập 1 - Trang 669-674 vol.1
Tóm tắt
Describes the current effort of creating cooperative analog/digital signal processing (CADSP) systems towards auditory sensor and signal processing applications. We address resolution issues that affect the choice of signal processing algorithms arriving from an analog sensor. We discuss current analog circuit approaches towards the front-end signal processing. We discuss our current IC approaches using this technology for noise suppression, as well as our current analog signal processing front-end system for speech recognition. Experimental data is presented from circuits fabricated using a 0.5 /spl mu/m n-well CMOS process available through MOSIS.
