Abstract
Control system electronics is a key element in an active control system.
Conventionally, the active noise control systems have been sophisticated and
expensive laboratory units. Only few real-world applications, such as active
headsets and active control units for ventilation noise attenuation have
existed with their matching commercial, integrated control systems. Latest
achievements in electronics, such as new, powerful signal processors, gate
arrays and even programmable analog gate arrays lead to new possibilities for
realization of modern control systems, suitable also for cost sensitive
applications. Also the analog-to-digital interfaces have recently advanced
considerably and cost per channel has dropped. Besides, advances in consumer
and automotive electronics and miniaturization have brought new possibilities
for developing the real-life, commercial control system for active noise
attenuation. These aspects have been addressed concurrently in our review
study. The latest possibilities of the control system electronics for single
and multichannel control schemes in both digital and analog domain are
introduced and their usability evaluated. Furthermore, the tools for designing
modern electronics for active noise control systems are presented.
